▼ Estrogens play crucial roles in regulating gene expression in physiological and disease states. Estrogens acts through estrogen receptors (ERs) and their binding sites in genomic DNA to modulate transcription by RNA polymerase II. Although recent gene-specific and genomic analyses have provided considerable information about of estrogen-dependent transcription, many aspects of the estrogen signaling network have not yet been elucidated. The goal of my studies was to uncover new information about the immediate and direct effects of estrogen signaling at the cell membrane, in the cytoplasm, and in the nucleus to elucidate the underlying regulatory networks. First, I investigated an ER transcriptional coregulators, SWI/SNF, an ATPdependent chromatin remodeling complex. I explored the molecular functions of the BAF57 and BAF180 subunits of SWI/SNF using a quantitative proteomic approach called SILAC (Stable Isotope Labeling by Amino Acids in Cell Culture). I found that depletion of BAF57 results in a significant depletion of BAF180 from the SWI/SNF complex without decreasing the total cellular BAF180 levels, resulting in an accumulation of cells in the G2/M phase. Knockdown of BAF57 also causes transcriptional misregulation of cell cycle-related genes involved in the late G2 checkpoint. Collectively, these studies have elucidated the role of BAF57 and BAF180 in the transcriptional control of cell proliferation. Second, I have used GRO-Seq (Global Nuclear Run-On and Massively Parallel Sequencing) to explore the immediate effects of estrogen signaling on the transcriptome of breast cancer cells. I found that estrogen directly regulates a strikingly large fraction of the transcriptome in a rapid, robust, and unexpectedly transient manner. In addition to protein coding genes, estrogen regulates the distribution and activity of all three RNA polymerases, and virtually every class of non-coding RNA that has been described to date. I also identified a large number of previously undetected estrogen-regulated intergenic transcripts, many of which are found proximal to ER[alpha] binding sites. These results provide the most comprehensive measurement of the primary and immediate estrogen effects to date. I expect that genome-wide inferences based on the direct estrogen-regulated transcriptome in combination with estrogen-regulated signaling pathway will be useful for understanding estrogen biology.

▼ Tissue transglutaminase (tTG) is a GTPase and acyl transferase which catalyzes the formation of covalent crosslinks between two protein substrates. tTG expression and activation are frequently up-regulated in different types of human cancer, where it has been shown to be important for enhancing cell motility. Using HeLa cervical carcinoma cells as a model system, I show that a membrane-associated pool of tTG becomes activated and re-distributes to the leading edges of migrating cells upon EGF stimulation. Immunoprecipitations of tTG from the membrane fractions of EGF-treated HeLa cells led to the discovery that tTG binds the heat shock protein (Hsp)70 family of molecular chaperones. tTG and Hsp70 co-localize at leading edges, and this localization is dependent on the ATP hydrolytic activity of Hsp70, as inhibitors against this function prevent both tTG and Hsp70 from localizing to leading edges. More importantly, these inhibitors also block the EGF-dependent migration of HeLa cells and the constitutive migration of MDA-MB231 cells, suggesting that Hsp70 helps localize tTG to leading edges to facilitate its role in promoting cell migration. While tTG has been shown to influence a number of aspects of cancer progression, to what degree tTG works with oncogenic proteins to elicit these outcomes versus its intrinsic ability to impact malignant transformation is unknown. Thus, I have examined how ectopic expression of tTG in a normal (non-transformed) cellular context influences the behavior of these cells. Using NIH3T3 fibroblasts stably expressing the vector alone or a Myc-tagged form of wild-type tTG, I found that tTG strongly protected these cells from serum-starvation-induced apoptosis by activating the PI3-kinase/mTOR/p70 S6-kinase pathway. tTG binds c-Src and PI3kinase, and the formation of this complex is critical for the activation of the PI3-kinase signaling pathway. Activation of PI3-kinase signaling is essential for tTG's ability to promote cell survival, as inhibition of any component in this pathway, including Src, PI3-kinase, or mTOR, eliminates the protective effect afforded to the cells by tTG expression.

▼ In order for fibroblasts to migrate, budding yeast to polarize, and macrophages to undergo phagocytosis, each cell must coordinate a membrane-localized signal with a robust morphological change. The Rho Family of GTPases play critically important roles in mediating these cellular processes. However, in order for the Rho GTPases to help regulate these processes in a tightly coordinated spatial and temporal manner, they need to be properly localized to specific membrane signaling sites. The mechanisms by which this precise localization is achieved are still not fully understood, but represent the subject of this thesis. The Rho GTPases are post-translationally modified at their C-terminus by the covalent attachment of a 20 carbon lipid tail, called a geranylgeranyl moiety, which allows them to associate with membranes. To facilitate their cytosolic localization, the Rho GTPases require the assistance of a ubiquitously-expressed regulatory protein, the Rho guanine nucleotide-dissociation inhibitor (RhoGDI). The mechanism by which the Rho GTPases move between distinct locations in the cell, and in particular, how they are able to cycle on and off between different membranes, has been a challenging question. I have set out to begin to define this mechanism by reconstituting in vitro the interactions between the geranylgeranylated Rho GTPase Cdc42, RhoGDI, and liposomes of well-defined lipid composition. In taking advantage of the sensitivity and real-time capabilities of these reconstituted systems, some unexpected findings emerged regarding how RhoGDI influences the membraneto-cytosol distribution of Rho GTPases like Cdc42. One such unexpected discovery involves my finding that RhoGDI can distinguish between the signaling-inactive (GDP-bound) and signaling active (GTPbound) forms of Cdc42 when they are associated with a lipid bilayer. In particular, despite having similar affinities for the GDP- and GTP-bound forms of Cdc42 in solution, I found that when RhoGDI interacts with Cdc42 along the membrane surface, it has a much higher affinity for GDP-bound Cdc42 compared to its GTPbound counterpart. Moreover, the membrane-release of Cdc42-RhoGDI complexes occurs at a similar rate as the release of Cdc42 alone, with the major effect of RhoGDI then being to significantly slow the re-association of Cdc42 with membranes. These findings lead us to propose a new model for how RhoGDI influences the ability of Cdc42 to move between membranes and the cytosol. I further demonstrated that the cycling of Rho GTPases like Cdc42 and Rac1 between the membrane and cytosol can be strongly influenced by RhoGEFs and RhoGAPs, as well as RhoGDI, such that the membrane association-dissociation cycle of the Rho GTPases is directly coupled to their GTP-binding/GTPase cycle. Most of the Rho family GTPases contain a cluster of positive-charged residues (i.e. a 'polybasic domain'), directly preceding their geranylgeranyl moiety. It has been suggested that this domain serves to fine-tune their localization among different cellular membranes. I have…

▼ A family of water soluble and positively charged L-arginine based poly (ester amide)s (Arg-PEAs) was synthesized by solution polycondensation. These biodegradable Arg-PEAs consist of 3 nontoxic building blocks: L-arginine, diols and dicarboxylic acids. The Arg-PEAs were prepared by the reaction of tetra-p- toluenesulfonic acids salts of bis-(L-arginine) [alpha], [omega]-alkylene diesters and di-pnitrophenyl esters of dicarboxylic acids. Optimal conditions of the monomers and polymers synthesis were investigated, and the monomers and Arg-PEAs were chemically characterized. Arg-PEAs were found to have good solubility in water and many other polar solvents. . Arg-PEAs were evaluated by many biological assays for the gene delivery applications. Structure-function relationship of the Arg-PEAs revealed that changing the number of methylene groups in the diol or/and diacid segment could finely tune the hydrophobic and cationic properties of the Arg-PEAs, and then affect the gene delivery efficiency. MTT assay showed that all the prepared Arg-PEAs and Arg-PEA/DNA complexes were non-toxic to the cell lines even at very large doses. Some of Arg-PEAs showed comparable or higher transfection efficiency than the commercial transfection agents, Superfect® and Lipofectamine2000®. Based on the above results, a new generation of Arg-PEAs, oligoethylene glycols and L-arginine based poly (ether ester amide)s (Arg-PEEAs) were developed. The new Arg-PEEAs had more flexible chain due to the introduction of oligoethylene glycols. Structure-function relationship of the Arg-PEEAs was intensively studied. MTT assay showed that all the and Arg-PEEA/DNA complexes were non-toxic to the cell lines, primary cells and stem cells even at very large doses. The Arg-PEEAs expanded the gene transfection from cell lines to primary cells/stem cells, and showed comparable or higher transfection efficiency than the commercial transfection agents, Superfect® and Lipofectamine2000®. Arg-PEAs with double bond functionality (Arg-UPEAs) could be photocrosslinked with Pluronic- diacrylate (Pluronic-DA) to form cationic hybrid hydrogels. The physicochemical and mechanical properties of the hybrid hydrogels were studied. The fibroblast and endothelial cells were cultured on the hybrid hydrogel surface and inside the hydrogel, respectively. The results indicated that the introduction of ArgUPEAs could significantly increase the cell attachment performance on hydrogel surface and viability inside the hydrogel. Some new L-phenylalanine based poly (ester amide)s (Phe-PEA) or derivatives were developed as the coating materials causing low inflammatory response. One example is the block copolymer of Phe-PEA and poly ([epsilon] -caprolactone) (PCL) [PEAb-PCL], another example is the L-Arginine and L-phenylalanine based hybrid poly (ester amide)s (Arg-Phe-PEAs). The new biomaterials were characterized and studied the cellular responses, such as cell attachment and macrophage inflammatory response. The results indicated that they could promote the cell attachment and cause…

▼ An increasing number of cellular activities are under the regulation of lysine acetylation. This post-translational modification (PTM) is reversibly catalyzed by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Targeting these enzymes to different cellular compartments is instrumental in defining their substrates and functions in vivo. Here we showed that a S. cerevisiae HDAC Hos3 is asymmetrically targeted to the daughter side of the bud neck and to the daughter spindle pole body (SPB). Screening for mutants defective in targeting Hos3 to the bud neck identified septins and members of the morphogenesis checkpoint, pinpointing Hsl7 as the protein that recruits Hos3 to the bud neck. When spindle orientation defect is present, Hos3 is loaded symmetrically onto both SPBs. Importantly, although the neck localization of Hos3 is dispensable for a number of cellular activities, it is required for the response of Hos3 to spindle misorientation. When symmetrically associated with both SPBs, Hos3 may function as a spindle position checkpoint (SPOC) component to inhibit mitotic exit. The results together reveal how a uniquely targeted HDAC Hos3 functions as crosslink between the morphogenesis checkpoint and the SPOC. On a more general perspective, this study substantiates an important role of lysine acetylation in monitoring spindle orientation and regulating the cell cycle.

▼ Heregulin (HRG) is a growth factor that mediates the activation of ErbB2/ErbB3 receptors. Aberrant signaling of HRG and the ErbB receptors give rise to human cancer. Our laboratory has previously identified mammalian target of rapamycin (mTOR), an essential hub for growth factor and nutrient sensing, as an important intermediate in HRG-signaling. This thesis focuses on the pathways that lead to the activation of mTORC1 (mTOR complex 1) in response to HRG. First, I identified the importance of mTORC2 signaling to mTORC1 in ErbB2/HRGmediated cellular transformation in SKBR3 breast cancer cells. mTORC2 was initially identified to play a role in actin cytoskeletal remodeling, but with the discovery of novel mTORC2 targets, mTORC2 has been implicated in cellular functions such as cell proliferation, survival, and metabolism. By utilizing rapamycin and an ATP-competitive inhibitor of mTOR, INK128, I was able to differentiate between mTORC1 and mTORC2 activation by HRG. In HRG/ErbB2mediated signaling to AKT, mTORC2 is required for the phosphorylation on AKT (S473) and this precedes the activating PDK1 phosphorylation at AKT (T308). AKT phosphorylates TSC2, making TSC2 unable to function on Rheb. Rheb remains in its GTP-bound form and activates mTORC1. By performing a Rictor knock-down, which decreased mTORC2 availability in the cell, the HRG-mediated transforming capability of SKBR3 cells was reduced. Next, I took a mechanistic approach to identify how small GTPases, namely Rheb, Rac, and i Cdc42, are playing a role in HRG-mediated mTORC1 activation. Using a knock-down and rescue approach, I was able to delineate that Rac and Cdc42 are upstream of Rheb, and that they signal independently of one another to mTORC1 in this context. Additionally, I found that Dock7, a GEF for Rac and Cdc42, serves as a unique scaffold for the G-proteins and mTORC1. The most intriguing finding, however, is that Dock7 also possesses properties of a Rheb GEF. It has long been hypothesized that only a GAP is needed for the regulation of Rheb, so the identification of a putative Rheb GEF is of significant interest to the field. ii

▼ Gonadotropin releasing hormone (GnRH) is the central hormone of reproduction in vertebrates. This hormone is secreted from the hypothalamus in response to environmental, steroid hormone feedback and other stimuli in a pulsatile manner and travels via the hypophyseal portal vasculature to the anterior pituitary. GnRH binding to its receptor on the surface of pituitary gonadotropes stimulates the release of the gonadotropin hormones: luteinizing hormone (LH) and follicle stimulating hormone (FSH), heterodimers of the common [alpha] subunit with the hormone-specific [beta] subunits. In addition to secretion of gonadotropin hormones, GnRH stimulates the transcription of the gonadotropin subunit genes and that of its own receptor (GnRHR). The GnRHR has been shown in recent years to be a constitutive occupant of membrane raft microdomains within the plasma membrane. GnRHR association with these microdomains appears to be required for the initiation of downstream signaling processes within the GnRH signaling network including activation of the mitogenactivated protein kinase, extracellular signal regulated kinase (ERK). GnRHR-induced ERK activation is absolutely required for gonadotropin subunit gene expression and fertility in mice. In this dissertation the components of the GnRHR-associated membrane raft microdomain are explored providing insight into how the receptor might be connected to membrane microdomains, the actin cytoskeletal network, and the initiation of downstream transcriptional events. These studies introduce the flotillin/reggie proteins and [beta] catenin as novel members of the GnRHR-associated membrane raft proteome in addition to identifying a list of proteins for future studies.

▼ A major feature of a eukaryotic cell is its ability to compartmentalize its functions by sequestering components into distinct membrane-bound organelles. Since membrane-embedded proteins cannot diffuse through the cell to travel between organelles, they must be sorted into transport vesicles, typically by coat complexes and their adaptors. The transmembrane protein Chitin Synthase 3 (Chs3) in Saccharomyces cerevisiae is an excellent model system to study some of these complex sorting and transport processes. Chs3 cycles between specific locations on the plasma membrane (PM) where it synthesizes chitin for the yeast cell wall, and retention in trans-Golgi network (TGN) compartments where it is inactive. Exomer, a novel protein complex found in fungi, acts as an adaptor complex for the transport of Chs3 and several other proteins from the TGN to the PM. The exomer complex is composed of the core subunit protein Chs5 and paralagous adaptor proteins known as ChAPs (Chs5-Arf1-binding Proteins), and is recruited to the membrane by the small GTPase Arf1. I have determined the minimal functional fragment of Chs5, which I have shown interacts with Arf1, likely contributing to exomer recruitment. The ChAPs are responsible for binding cargo, and Chs6 is required for transport of Chs3. Therefore, I examined Chs6 protein levels throughout the cell cycle and incorporation into complexes. When Chs6 levels were held constant by replacing its promoter with another, there was an effect on Chs3 transport only in one yeast background, indicating this regulation is only required under certain conditions. I also show that different segments of the Chs3
N-terminus mediate distinct trafficking steps. I present a crystal structure of residues 10-27 bound to the exomer complex, which are residues known to mediate retention and also seem to play a role in internalization. Residues 2852 are involved in transport to the plasma membrane and recycling out of the endosomes to prevent degradation. Together, these findings contribute to our understanding of how proteins are transported by exomer, and how cycling of a transmembrane protein can be regulated.

▼ Replication errors that escape DNA polymerase proof-reading activity are efficientl y recognized and repaired by conserved DNA mismatch repair factors. The overall result is a drastic reduction in deletion mutations. The mechanistic details of how mismatch repair proteins execute mismatch removal have not been elucidated. The aim of my thesis is to better understand how mismatch repair factors interact with DNA in order to identify mismatch sites. My work reveals that the mismatch repair complex, MLH1-PMS1, has unique DNA diffusion characteristics facilitated by structural features of the two subunits. Through bulk assays and total internal reflectance fluorescence microscopy (TIRFM), I found that MLH1PMS1 could independently bind DNA and rapidly diffuse using the thermal energy of the system. Furthermore, MLH1-PMS1 was shown to be the first passively diffusing protein that could bypass stationary nucleosomes. In contrast, the DNA diffusion activity of the mismatch recognition complex MSH2-MSH6 was blocked by nucleosomes. The timing and nature of mismatch repair is linked with replication and is thus proposed that the differences seen for the two complexes have important implications for repair in the context of the chromatin state directly at the replication fork. Each subunit of the MLH1-PMS1 complex is composed of two defined globular domains connected by an unstructured linker arm. The linker arms of the complex are proposed to facilitate topological DNA binding and diffusion along DNA in a hopping/stepping mechanism. I found that TEV protease cleavage within the linker arms of MLH1-PMS1 disrupted DNA binding and mismatch repair in vitro and in vivo. Using a genetic mismatch repair assay I found that shortening of the linker arms in MLH1 had a drastic effect on function whereas similar changes in PMS1 had little or no effect. Purified truncated complexes were able to interact with DNA and form ternary complexes with MSH2-MSH6 at a mismatch. Future studies should focus on the diffusion characteristic for these complexes. Together, my work has important implications for understanding how mismatch repair proteins can rapidly identify their targets in a chromatin landscape.

▼ Poly(ADP-ribosyl)ation (PARylation) is an enzymatic reaction whereby ADPribose units from donor NAD+ molecules are covalently attached onto target proteins. The regulation of this reaction is overseen by two nuclear enzymes, Poly(ADP-ribose) polymerase-1 (PARP-1) and poly(ADP-ribose) glycohydrolase (PARG), that modify target proteins in the nucleus by the addition and removal, respectively, of ADP-ribose polymers. While PARP-1 has generally been studied with respect to its role in DNA damage repair and cell death pathways, recent studies have revealed a role for PARP-1 in transcriptional regulation. The role of PARG in transcriptional regulation, however, is less characterized. In this study, I have investigated the coordinate patterns of gene regulation by PARP-1 and PARG in vivo using genomic and gene-specific analyses. Specifically, I show that PARP-1 and PARG coordinately regulate global patterns of gene expression by affecting genes in the same direction and with similar magnitudes. Further analysis revealed that PARP-1 and PARG localized to the promoters of both positively and negatively regulated target genes in parallel binding patterns. I also show that PARP-1 and PARG enzymatic activities are required for some, but not all, target genes. My results indicate that PARP-1 and PARG, two nuclear enzymes with opposing enzymatic activities, localize to target promoters and act in a similar, rather than antagonistic, manner to regulate gene expression. In a follow-up study, I have used a novel method known as Global Run-on Sequencing (GRO-seq) to define the role of PARP-1 on the estrogen-regulated transcriptome at the level of the nascent transcript, rather than steady-state mRNA levels. I have produced libraries from MCF-7 cells treated with vehicle or 17[beta]estradiol (E2) under three conditions: (i) a control knockdown; (ii) a control knockdown plus a PARP inhibitor, PJ34; and (iii) a PARP-1 knockdown. I have determined that the estrogen response is highly maintained under PARP-1 knockdown or inhibition. Accordingly, upon estrogen treatment, PARP-1 localization patterns are largely unaffected. However, deeper analyses reveal a small number of genes where PARP-1 knockdown or inhibition reduces the estrogen response at the transcription level (GRO-seq) and at the steady state mRNA level (RT-qPCR). The NAD+ metabolite generated from the PARP-1/PARG reaction, ADPribose (ADPR), is a small molecule ligand that is used by macro domain-containing proteins. The histone variant macroH2A1 is one such protein that has generally been studied with respect to its role in transcriptional repression on the inactive X chromosome. However, recent studies have begun to explore a role for macroH2A1 in autosomal gene regulation, as a transcriptional repressor and a transcriptional activator. Recent results from the Kraus lab have shown that the transcriptional coactivator Proline-, glutamic acid-, and leucine-rich protein 1 (PELP1) interacts with the macro domain of macroH2A1 in a ligand-independent manner and shows a similar…

▼ The polarization of proteins, lipids, and organelles within a eukaryotic cell allows for the spatial regulation of numerous biological processes. Saccharomyces cerevisiae displays exaggerated polarized growth of its plasma membrane during budding through the directed transport of secretory vesicles. In addition, several organelles are actively transported into the growing bud. These processes are accomplished using formin-nucleated actin cables extending from the bud tip and neck and the myosin-V motor Myo2p. While many of the components linking Myo2p to its various cargoes are known, the dynamic behavior of the motor and how its dynamics is regulated at the molecular level remains unclear. Here I define the in vivo delivery cycle of a myosin-V in its essential function of secretory vesicle transport, and show how that transport is coordinated with other events in exocytosis. I determined that Myo2p is activated from an inactive state by binding to competent secretory vesicles. This inactive state is caused by an autoinhibitory interaction between the head and tail of the motor. Mutations that disrupt this interaction render the motor constitutively active and compromise cargo transport functions. About 10 motors associate with each secretory vesicle during rapid transport to sites of cell growth. Motor release is temporally regulated by vesicle-bound Rab-GTP hydrolysis and requires vesicle tethering via the exocyst complex, but does not require vesicle fusion with the plasma membrane. Additionally, I developed a vesicletracking assay to study single-vesicle fusion dynamics at the cortex. This aided in the creation of a timeline of events for exocytosis, allowing for the dynamics of single-vesicle populations of the Rab Sec4p, the exocyst complex, and Myo2p to be visualized. The components of this transport cycle are highly conserved in mammalian cells, so these results should be generally applicable to other myosin-V delivery cycles.

▼ Excessive cellular reactive oxygen species (ROS), or oxidative stress, can lead to cell damage and is implicated in diseases such as cancer, aging and neurodegenerative disorders. Yet, although these highly reactive molecules can be damaging, ROS can also elicit beneficial effects in cells as signaling molecules. In the endoplasmic reticulum (ER), where ROS are produced from protein folding, the Hsp70 BiP plays a role in cell protection during ER oxidative stress. BiP is a chaperone that binds and release substrates, and these activities are regulated by its ATPase cycle. We have previously discovered that yeast BiP’s conserved cysteine gets modified by the ROS peroxide during oxidative stress conditions. Our lab discovered that the protein Sil1 functions in cells as a reductant that can remove the modification on BiP’s cysteine. The reductant activity of Sil1 is mediated through two
N-terminal cysteines. Sil1 has been well- characterized as BiP’s nucleotide exchange factor (NEF) that facilitates ADP release. Sil1 is active as a NEF even in the absence of its
N-terminal region. A molecular picture as to how the
N terminus, which contains the redox-active cysteines, influences interaction with BiP remains unclear. Our biochemical characterization of the full-length Sil1 has revealed that the
N-terminal domain plays a role in modulating Sil1 activities. We uncovered that the presence of the
N-terminal domain decreases Sil1 NEF activity and impacts the structural conformation adopted by full-length Sil1. We have mapped the region of the
N terminus that accounts for the auto-inhibition of Sil1 NEF activity to a stretch of 36 amino acids of highly conserved sequence. Mutations in human SIL1 have been found in patients with Marinesco-Sjogren syndrome (MSS). One such mutation, R92W, is in the conserved
N-terminal region. Through the characterization of the yeast version, Sil1-R84W, we have demonstrated that the mutation increases NEF activity, impacts reductant activity, and changes the apparent conformation of Sil1. Our overall findings suggest that the
N-terminal domain’s conserved region is important in regulating Sil1 activities. We predict that this region may undergo post-translational modifications in cells to modulate NEF and reductant functions of Sil1 under specific physiological conditions.

▼ Notch signaling plays an important role in regulating olfactory neurogenesis during development of the mammalian subventricular zone. During development, the Notch signaling pathway is critical for maintenance of neuronal precursors, cell survival, and for neural stem/progenitor cell self-renewal. Notch receptors have been shown to be expressed among the heterogeneous populations of cells in the subventricular zone. However, the regulation of Notch remains poorly understood. In the subventricular zone, the Notch activator Jagged1 has been shown to be expressed in cells adjacent to those expressing Notch receptors. Moreover, a previous study showed that Jagged1 is important for self-renewal of neural stem cells in the subventricular zone during postnatal stages. We utilized a conditional Jagged1 knockout mouse to study the role of Jagged1 in the embryonic subventricular zone. We found that Jagged1 is critical for olfactory neurogenesis during development. Jagged1 mutants exhibited a decrease in the production of neuronal precursors and olfactory interneurons. Additionally, we observed that the loss of Jagged1 increases cell death in the rostral migratory stream, a specialized migratory stream connecting the subventricular zone and the olfactory bulb. Finally, we show that Jagged1 is expressed on neural stem cells. Based on these findings, Jagged1 is proposed as a critical regulator of neurogenesis in the embryonic subventricular zone.

▼ IL-2-inducible T cell kinase (ITK) is expressed in T lymphocytes and mast cells (MC), and functions as a critical signaling mediator downstream of numerous cell surface receptors. ITK regulates both adaptive and innate immunity, via regulation of cell differentiation and activation. Lack of ITK results in spontaneous memory acquisition in [alpha][beta] T cells termed "innate memory phenotype (IMP) T cells". The development and function of IMP T cells, and the role of ITK in their development remains unknown. This dissertation describes an alternative bone marrow transplantation system, which generates murine models with predominant naïve or IMP T cells, allowing comparative investigation of the functions of these cells in vivo; and demonstrates that: 1) IMP T cell development requires hematopoietic expression of major histocompatibility complexes; 2) IMP CD8+ T cells are not the result of T cell homeostatic proliferation (HP), and they can rapidly and potently respond to primary antigenic stimulation; and 3) IMP CD4+ T cells can suppress autoimmune graft-versus-host disease. In addition, this dissertation also investigates the T cell-intrinsic role of ITK in the development of both IMP and HP CD8+ T cells: 1) ITK tunes IL-4/TcR signaling synergy to regulate IMP CD8+ T cell differentiation; and 2) ITK suppresses CD8+ T cell HP and anti-tumor immunity. Loss of ITK in mice also results in hyper-production of immunoglobulin E (IgE), through which MC regulate the development of allergy. Differential functions of ITK and the homologous Bruton's tyrosine kinase (BTK) in MC response to allergen/IgE-mediated stimulation have been illustrated. This dissertation further shows a redundant function for ITK/BTK in MC response to the bacterial endotoxin lipopolysaccharide (LPS), in that lack of ITK and BTK leads to hyper-production of MC-derived TNF-[alpha], which exacerbates LPS-induced septic hypothermia. This work provides insights into the function of ITK in innate T cells, and the value of targeting ITK to enhance antigen-specific primary response by IMP CD8+ T cells, regulatory function of IMP CD4+ T cells, and expansion of anti-tumor HP CD8+ T cells, for therapeutic purposes. However, the MC response to LPS also raises concern on the potential use of ITK/BTK cross-reactive kinase inhibitors.

Thus, cells maintain a "cradle to grave" quality monitoring system for integral membrane proteins, yet the mechanisms of iii quality surveillance, particularly at the PM, remain poorly understood. Here we present evidence that the E3 ubiquitin ligase Rsp5, the yeast homolog of Nedd4, is part of a critical protein quality surveillance mechanism at the PM. We show that proteotoxic stress triggers global activation of Rsp5-dependent ubiquitination, endocytosis, and vacuolar trafficking of PM proteins. Mutants defective for this protective response exhibit toxic accumulation of integral membrane proteins at the cell surface and suffer catastrophic loss of PM integrity during misfolding stress, phenotypes that can be suppressed by the presence of chemical chaperones. We present the identification of specific Rsp5 adaptors which target the ubiquitination of misfolded PM proteins during proteotoxic stress. Genetic interaction analysis reveals that this PM quality surveillance mechanism exhibits striking synthetic defects with components of both ERAD and the unfolded protein response, indicating that different quality control pathways cooperate to protect cells during misfolding stress. We propose that this ubiquitin-mediated PM quality surveillance pathway, together with other quality control pathways like ERAD, protects cells from proteotoxic stress by limiting the toxic accumulation of misfolded integral membrane proteins at the PM. iv

▼ A defining feature of eukaryotic life is the presence of membrane-bound organelles. While the energetically most stable shape for a membrane is likely a sphere, many organelles possess much more complex shapes within cells which contributes to their proper function. There has been an explosion in the field of membrane bending proteins in recent years giving new insights into how a cell forms and maintains organelle structures. Two ER resident proteins have recently been implicated in the formation of the tubular network of the ER in both higher and lower eukaryotes. Both Rtn1p and Yop1p contain two long hydrophobic domains, ~40 amino acids in length, which are thought to act as wedges within the outer leaflet of the ER membrane and drive membrane deformation. Using a mutagenic approach I have determined that both of the hydrophobic domains of Yop1p are critical for its ability to generate the tubules of the peripheral ER. The overexpression of Yop1p produces long, unbranched tubules in cells. I have developed an initial strategy for the enrichment of these Yop1p formed tubules for further study outside the context of the cell. Biochemical analysis of these tubular structures has revealed they are composed of protein and lipid components. Electron microscopy of enriched tubules indicates they have a small diameter, ~15 nm, and are often bundled together into rope-like structures. This work underscores the importance of Yop1p in the generation of the tubular network of the peripheral ER and provides evidence deepening our understanding of the molecular mechanism of Yop1p action on membranes that generates membrane tubules.

▼ Protein domains are the basic functional modules that maintain cell functions at a molecule level. Previous studies have mainly focused on the functions of isolated protein domains. The general objective of this thesis is to understand functions and regulations of multi-domain containing proteins. The study is based on two protein classes: naturally occurred BAR domain-containing proteins and artificially engineered calcium indicators. BAR domain super-family proteins BAR (Bin/Amphiphysin/Rvs) domain super-family proteins are peripheral membrane proteins that regulate membrane curvatures during the membrane remodeling events such as endocytosis, vesicular trafficking and cell growth. Via multiple biophysical approaches, I systematically studied BAR domain functions in Sorting Nexin 9, Endophilin and Pacsins at the presence of other protein domains. Two major findings are presented in this thesis. First I show that the diverse membrane sculpture activity of BAR domains is encoded in their unique molecular structures, and is influenced by membrane properties. Second, I show that this function diversity is highly regulated by other protein domains. Some protein domains have synergetic effects and play important roles in regulating cellular membrane remodeling. This work is significant in that it provides the molecular basis for the functional diversity of BAR domains and established the regulatory mechanism of BAR domain mediated-membrane deformation process. Genetically Encoded Calcium Indicators Genetically encoded calcium indicator GCAMP is an artificially designed multi-domain containing protein that can be endogenously expressed in cells to monitor calcium signals. The molecular mechanisms of its signal response and fast kinetics are poorly understood. Using fluorescent spectrometry and site-directed mutagenesis, I show that the calcium-dependent brightness of GCAMP is due to the different protonation states of the chromophore. Structural characterization of GCAMP reveals that the calmodulin domain regulates chromophore protonation states via a sophisticated water-mediated hydrogen bond network. This finding provided a general scheme for designing GCAMP-like sensors. Furthermore, I show that distinct electron properties of the protonated and deprotonated chromophore can be applied to design color switchable fluorescent proteins. This finding provides a novel approach to design the ratio metric pH sensors with an improved sensitivity.

▼ The budding yeast Saccharomyces cerevisiae shows substantial polarity during its growth. Membranes and proteins are constantly transported to the growth sites, almost exclusively mediated by the Myosin motor Myo2p. Myo2p recognizes its cargos by interacting with different cargo-specific adaptors and its function also relies on other accessory proteins. Among them, the kinesin-like protein Smy1p was interesting due to its genetic interactions with sec2, sec4 and myo2 mutants. However, current models have problems reconciling all the previous findings. Whether Smy1p has a function in polarized secretion and how Smy1p exerts its function are largely unknown. To address these questions, different approaches were employed in this research. First, Smy1p localization was determined and I found it to rely on interactions with Myo2p. Further truncation analysis revealed a complicated localization and expression level regulation. Second, Smy1p protein depletion in myo2 conditional mutants was found to cause a massive secretion block and this method can be applied to other mutants like sec2-56, sec4-8 as well. Third, I identified over 30 smy1 mutants in different myo2 sensitized strains, studying of which will greatly increase our understanding of the mechanism underlying Smy1p's function.
