Background: Rab10 is a member of the Ras superfamily of small Rab GTPases (1) that interacts with Mss4, myosin V (Va, Vb and Vc) and GDI as it helps mediate sorting among cellular endosomes (2-4). Mutation analysis and GFP-fusion protein expression of Rab10 in MDCK cells determined that Rab10 plays a regulatory role in membrane protein transport between early endosomes and basolateral compartments (5,6). Rab10 associates with the GLUT4 complex as a target for AS160 and is required for insulin-stimulated GLUT4 translocation in adipocytes (7,8).

Background: Synaptotagmin 1 (SYT1) is an integral membrane protein found in synaptic vesicles thought to play a role in vesicle trafficking and exocytosis (1). Individual SYT1 proteins are composed of an amino-terminal transmembrane region, a central linker region and a pair of carboxy-terminal C2 domains responsible for binding Ca2+ (2). The C2 domains appear to be functionally distinct, with the C2A domain responsible for regulating synaptic vesicle fusion in a calcium-dependent manner during exocytosis while the C2B domain allows for interaction between adjacent SYT1 proteins (3). Because synaptotagmin 1 binds calcium and is found in synaptic vesicles, this integral membrane protein is thought to act as a calcium sensor in fast synaptic vesicle exocytosis. Evidence suggests possible roles in vesicle-mediated endocytosis and glucose-induced insulin secretion as well (4,5). SYT1 binds several different SNARE proteins during calcium-mediated vesicle endocytosis and an association between SYT1 and the SNARE protein SNAP-25 is thought to be a key element in vesicle-mediated exocytosis (6).

Background: Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11).

Background: Fatty acid binding proteins (FABPs) bind to fatty acids and other lipids to function as cytoplasmic lipid chaperones (1). They participate in the transport of fatty acids and other lipids to various cellular pathways (2). Differential expression of FABPs is found in several types of tumors and their normal-cell counterparts (3). FABP7 is abundantly expressed in fetal brain and may be essential for development (4). Expression is required for the establishment of the radial glial fiber system, a system that is necessary for the development of cortical layers (5). Increased expression of FABP7 is associated with reduced survival in patients with glioblastoma (6), and is also found in glial cells following nerve injury (7). Investigators have found loss of FABP7 may be involved in the development and progression of breast cancer and expression of FABP7 has been shown to induce mammary differentiation and to inhibit growth of breast cancer cells (8,9).

Background: Receptor binding cancer antigen expressed on SiSo cells (RCAS1) is also known as estrogen receptor-binding fragment-associated gene 9 (EBAG9). Originally identified as an estrogen-inducible gene (1), RCAS1 was recently found to play a novel role in the adaptive immune response by negatively regulating the cytolytic activity of cytotoxic T lymphocytes (CTLs) (2). RCAS1 is conserved in phylogeny and is ubiquitously expressed in most human tissues and cells (3,4). There is evidence that tissue expression of RCAS1 is increased in a variety of malignancies, including cancers of the gastrointestinal tract, liver, lung, breast, ovary, endometrium, and cervix. Research studies have shown that levels of RCAS1 tissue expression are negatively correlated with the prognosis of patients harboring the aforementioned malignancies (4). It is also noteworthy that research studies have detected elevated levels of RCAS1 in the sera of cancer patients (4). Initial studies indicated that RCAS1 was secreted from cancer cells and functioned as a ligand for a putative receptor expressed on NK cells, as well as T and B lymphocytes, inducing their apoptosis, which enabled cancer cells to evade immune surveillance (5,6). Subsequent studies have identified RCAS1 as a type III transmembrane Golgi protein with the ability to regulate vesicle formation, secretion, and protein glycosylation (2,7-9). Indeed, it has been shown that RCAS1 overexpression negatively regulates the cytolytic function of CTLs by negatively regulating protein trafficking from the trans-Golgi to secretory lysosomes (2). Furthermore, RCAS1 overexpression delays vesicle transport from the ER to Golgi and causes components of the ER quality control and glycosylation machinery to mislocalize. As a consequence, RCAS1 induces the deposition of tumor-associated glycan antigens on the cell surface, which are thought to contribute to tumor pathogenesis through the mediation of adhesion, invasion, and metastasis (8,9).

Background: The Ras family small GTPase Ran is involved in nuclear envelope formation, assembly of the mitotic spindle, and nuclear transport (1,2). Like other small GTPases, Ran is active in its GTP-bound form and inactive in its GDP-bound form. Nuclear RanGTP concentration is maintained through nuclear localization of guanine nucleotide exchange factor (GEF) activity, which catalyzes the exchange of bound GDP for GTP. Regulator of chromatin condensation 1 (RCC1) is the only known RanGEF (3). RCC1 is dynamically chromatin-bound throughout the cell cycle, and this localization is required for mitosis to proceed normally (4,5). Appropriate association of RCC1 with chromatin is regulated through amino-terminal phosphorylation (5,6) and methylation (7). RCC1 regulation of RanGTP levels in response to histone modifications regulates nuclear import during apoptosis (8). In mitosis RCC1 is phosphorylated at Ser11, possibly by cyclin B/cdc2 (9-11). This phosphorylation may play a role in RCC1 interaction with chromatin and RCC1 RanGEF activity (6).

Background: PAR-4 (prostate apoptosis response-4) was identified as a protein that is upregulated in prostate tumor cells undergoing apoptosis (1). Additionally, in parallel studies PAR-4 was found in the yeast two-hybrid system to bind to the Wilms' tumor suppressor protein WT1 and may modulate WT1-medated transcriptional activation (2). PAR-4 contains a leucine zipper domain and a death domain and has been implicated as an effector of apoptosis during tumorigenesis as well as in neurodegenerative disorders (3,4). PAR-4 is widely expressed in normal tissues but can be downregulated in some tumor types. The mechanism of PAR-4 mediated apoptosis regulation appears to be complex and dependent on the cellular context. Studies have indicated roles for PAR-4 in activation of the Fas-FADD-caspase-8 pathway as well as inhibition of the NF-κB pro-survival pathway (5-7). Its activity is likely to depend on the cellular context and post-translational modifications. For instance, phosphorylation of PAR-4 by Akt prevents its nuclear translocation thereby promoting cell surivival (8). In contrast, phoshorylation of rat PAR-4 at T155 by PKA appears to positively regulate its apoptotic activity (9).

Background: CELSR2 (cadherin EGF LAG seven-pass G-type receptor, also known as flamingo homolog 3 or epidermal growth factor-like protein 2) is a member of the flamingo subfamily of non-classical cadherins, part of the cadherin superfamily. CELSR2 is a 7-transmembrane helix receptor that contains nine cadherin-like domains, seven EGF-like repeats, and 2 laminin A G-type repeats (1). It shares structural characteristics of both an adhesion molecule and a G protein-coupled receptor, suggesting putatives roles in both cell-cell adhesion and juxtacrine signaling. It's function has been associated with dendrite morphogenesis (2), neural plate anterior-posterior pattern formation (3), and regulation of transcription via the Wnt signaling pathway (4). In a loss-of-function mouse model, Celsr2 deletion resulted in defects in the planar organization of ependymal cilia, leading to defective cerebrospinal fluid dynamics and hydrocephalus (5). In humans, SNPs in the CELSR2 gene cluster on chromosome 1 have been associated with enhanced risk of coronary artery disease (6).

Background: Malic enzymes catalyze oxidative decarboxylation of malate to pyruvate (1). The malic enzyme family in mammalian cells includes the cytosolic malic enzyme 1 (ME1) and two mitochondrial malic enzymes (ME2 and ME3) (1, 2). ME1 and ME2 are critical for tumor cell growth and their expression is repressed by tumor suppressor p53 (2). Reduced expression of ME1 and ME2 reciprocally increases the levels and activation of p53, promoting p53-mediated senescence (2). Research studies show ME3 is essential for the survival of pancreatic ductal adenocarcinoma following genomic deletion of ME2 (3). Deletion of ME3 is lethal to ME2-null cancer cells, which has been suggested to provide a potential therapeutic opportunity using collateral lethality (3, 4).

EB1 is also found to associate with the adenomatous polyposis coli (APC) protein (5). Recent studies also suggest that EB1 plays a role in microtubule-based transport (6).

Background: Ubiquilin 1 (UBQLN1) is a ubiquitously expressed, type 2 ubiquitin like (UBL) protein that contains an amino-terminal UBL domain and a carboxy-terminal Ub-associated (UBA) domain (1). Research studies demonstrate that UBQLN1 associates with poly-Ub chains through its UBA domain, while the UBL domain participates in interactions with proteasome subunits. Evidence suggests that UBQLN1 acts as a shuttling factor during endoplasmic-reticulum-associated protein degradation (ERAD) as it transports misfolded, ubiquitinated proteins from the ER to the proteasome for subsequent degradation (2-5). Additional research studies demonstrate that the UBL domain of UBQLN1 binds UIM-containing endocytic proteins and participates in the sequestration of protein aggregates during aggresome formation (6,7). UBQLN1 regulates presenilin protein levels and is localized in neurofibrillary tangles of Alzheimer's disease-affected brains (8). Polymorphisms in the corresponding UBQLN1 gene may be associated with a risk of Alzheimer's disease (9-11).

It plays a role in formation of tight junctions in specialized cell types such as the slit diaphragm in the kidney glomerulus (4). CD2AP is also involved in the immunological synapse between CD2 expressing T cells and antigen presenting cells (5). It has been shown that interaction between CD2AP and other cytoskeletal proteins may regulate the endocytosis of EGFR (3).

Background: The most well characterized nuclear receptor corepressors are SMRT (silencing mediator for retinoic acid and thyroid hormone receptors) and its close paralog NCoR1 (nuclear receptor corepressor) (1,2). NCoR1 functions to transcriptionally silence various unliganded, DNA bound non-steroidal nuclear receptors by serving as a large molecular scaffold that bridges the receptors with multiple chromatin remodeling factors that repress nuclear receptor-mediated gene transcription, in part, through deacetylation of core histones surrounding target promoters. Indeed, the N-terminal portion of NCoR1 possesses multiple distinct transcriptional repression domains (RDs) reponsible for the recruitment of additional components of the corepressor complex such as HDACs, mSin3, GPS2, and TBL1/TBLR1. In between the RDs lies a pair of potent repressor motifs known as SANT motifs (SWI3, ADA2, N-CoR, and TFIIIB), which recruit HDAC3 and histones to the repressor complex in order to enhance HDAC3 activity (3). The C-terminal portion of NCoR1 contains multiple nuclear receptor interaction domains (NDs), each of which contains a conserved CoRNR box (or L/I-X-X-I/V-I) motif that allow for binding to various unliganded nuclear hormone receptors such as thyroid hormone (THR) and retinoic acid (RAR) receptors (4,5).Recent genetic studies in mice have not only corroborated the wealth of biochemical studies involving NCoR1 but have also provided significant insight regarding the function of NCoR1 in mammalian development and physiology. Although it has been observed that loss of Ncor1 does not affect early embyonic development, likely due to compensation by Smrt, embryonic lethality ultimately results during mid-gestation, largely due to defects in erythropoesis and thymopoesis (6). Another study demonstrated that the NDs of NCoR1 are critical for its ability to function in a physiological setting as a transcriptional repressor of hepatic THR and Liver X Receptor (LXR) (7).

Background: CHD8 belongs to the chromodomain helicase DNA-binding (CHD) family of ATP-dependent chromatin remodeling proteins (1). The CHD family of proteins has been shown to play an important role in regulating gene expression by utilizing the energy derived from ATP hydrolysis to alter chromatin architecture (1,2). The nine CHD family members are characterized by the presence of two tandem chromodomains in the N-terminal region and an SNF2-like ATPase domain near the central region of the protein (2-4). In addition, CHD8 contains three CR (conserved region) domains, a SANT (switching-defective protein 3, adaptor 2, nuclear receptor co-repressor, transcription factor IIB)-like domain, two BRK (brahma and kismet) domains, and a DNA-binding domain (2). The chromatin remodeling activity of CHD8 has been shown to be important for the regulation of a wide variety of genes, such as the HOX genes (5) and genes that are driven by β-catenin (6), p53 (7), estrogen receptor (8), or androgen receptor (9). CHD8 can also interact with the insulator binding protein CTCF and is required for CTCF insulator activity at multiple gene loci (10).

Background: The enzyme glutamate decarboxylase (GAD) is responsible for the synthesis of the essential neurotransmitter gamma-aminobutyric acid (GABA) from L-glutamic acid (1). GAD1 (GAD67) and GAD2 (GAD65) are expressed in nervous and endocrine systems (2) and are thought to be involved in synaptic transmission (3) and insulin secretion (4), respectively. Autoantibodies against GAD2 may serve as markers for type I diabetes (5). Many individuals suffering from an adult onset disorder known as Stiff Person Syndrome (SPS) also express autoantibodies to GAD2 (6).

Background: The tumor suppressor protein p21 Waf1/Cip1 acts as an inhibitor of cell cycle progression. It functions in stoichiometric relationships forming heterotrimeric complexes with cyclins and cyclin-dependent kinases. In association with CDK2 complexes, it serves to inhibit kinase activity and block progression through G1/S (1). However, p21 may also enhance assembly and activity in complexes of CDK4 or CDK6 and cyclin D (2). The carboxy-terminal region of p21 is sufficient to bind and inhibit PCNA, a subunit of DNA polymerase, and may coordinate DNA replication with cell cycle progression (3). Upon UV damage or during cell cycle stages when cdc2/cyclin B or CDK2/cyclin A are active, p53 is phosphorylated and upregulates p21 transcription via a p53-responsive element (4). Protein levels of p21 are downregulated through ubiquitination and proteasomal degradation (5).

Background: Ribosomal protein L5 (RPL5) is one of several proteins that comprise the 60S ribosomal subunit. RPL5 binds 5S rRNA and the nucleolar RPL11 protein to form the 5S ribonucleoprotein particle (RNP) that is incorporated into the large 60S ribosomal subunit (1). An RP-MDM2-p53 protein complex that contains ribosomal proteins RPL5, RPL11, and RPL23 acts as a nucleolar stress sensor that binds and inhibits MDM2 ubiquitin ligase activity and enhances p53-mediated transcriptional activity (2,3). RPL5 cooperates with RPL11 to influence ribosome biogenesis through regulating expression of the transcription factor c-Myc, which acts as the master regulator of ribosome biogenesis (4). Mutations in the corresponding RPL5 gene are associated with Diamond-Blackfan anemia, which is a form of red blood cell aplasia, and some cases of pediatric T-cell acute lymphoblastic leukemia (5,6).

Background: Chloride channel 3 (CLCN3) is a voltage-gated chloride channel (CIC) family protein that mediates H+/Cl- exchange across cell membranes. This 818 amino acid, multi-pass membrane protein is highly expressed in the brain and is especially abundant in the olfactory bulb, hippocampus, and cerebellum (1). CLCN3 protein localizes to endosomal compartments and synaptic vesicles where it contributes to vesicle acidification and proper synaptic vesicle neurotransmitter loading for GABAergic synaptic transmission (2,3). CAMKII-mediated phosphorylation of CLCN3 regulates chloride channel activity by regulating cell surface targeting of the CLCN3 chloride channel (4). Research studies show abnormally high CLCN3 expression at the cell surface of human glioma cells, and that CAMKII-dependent regulation of these channels contributes to glioma invasion (5).

Background: Astrin/SPAG5 was identified as a microtubule-associated protein in a mitotic extract (1). It is essential for cells to assemble biploar spindle structures and progress through mitosis (1, 2). Astrin/SPAG5 was also identified to be a component associated with outer dense fibers in the sperm tail (3). In addition, this protein negatively regulates mTORC1 activity during the cell stress response (4). Under stress conditions, Astrin/SPAG5 interacts with the mTORC1 component raptor and recruits raptor to stress granules, thereby suppressing mTORC1 formation (4). The inhibition of mTORC1 prevents its hyperactivation and thus keeps cells from undergoing apoptosis during stresses (4). Furthermore, Astrin/SPAG5 has been implicated to be a prognostic marker in breast cancer (5).

Background: Human DFF45 and its mouse homologue ICAD function in normal cells as chaperones for caspase-activated deoxyribonuclease (DFF40 or CAD) during its synthesis (1). The association of DFF45 (or its isoform DFF35) with DFF40 inhibits the DNAse activity of the latter (1-4). In vitro, DFF45 has been shown to be the target of several caspases, including caspase-3, -6, -7, -8 and granzyme B (3). In vivo, caspase-3 is believed to be the primary enzyme responsible for processing DFF45 and release of its carboxy-terminal fragment (3,5). The cleavage of DFF45 inactivates its inhibitory function on DFF40 and causes nuclear DNA degradation by DFF40, leading to cell death (6,7).

Background: Neurofibromatosis 2 (NF2) is an autosomal dominant, inherited disorder characterized by the occurrence of vestibular schwannomas, meningiomas, and other nervous system tumors. Both the familial tumors of NF2 and equivalent sporadic tumors found in the general population are caused by inactivation of the NF2 tumor suppressor gene. Merlin (moesin, ezrin, and radixin-like protein) is the NF2 gene product, displaying striking similarity to ezrin, radixin, and moesin (ERM) proteins. Regulation of merlin (also called schwannomin) and ERM proteins involves intramolecular and intermolecular head-to-tail associations between family members (1). Merlin and ERM proteins act as linkers between the plasma membrane and the cytoskeleton, affecting cell morphology, polarity, and signal transduction (2). Merlin is phosphorylated by the Rac/Cdc42 effector p21-activated kinase (PAK) at Ser518, negatively regulating Rac (3,4).

Background: Filamins are a family of dimeric actin binding proteins that function as structural components of cell adhesion sites. They also serve as a scaffold for subcellular targeting of signaling molecules (1). The actin binding domain (α-actinin domain) located at the amino terminus is followed by as many as 24 tandem repeats of about 96 residues and the dimerization domain is located at the carboxy terminus. In addition to actin filaments, filamins associate with other structural and signaling molecules such as β-integrins, Rho/Rac/Cdc42, PKC and the insulin receptor, primarily through the carboxy-terminal dimerization domain (1-3). Filamin A, the most abundant, and filamin B are widely expressed isoforms, while filamin C is predominantly expressed in muscle (1). Filamin A is phosphorylated by PAK1 at Ser2152, which is required for PAK1-mediated actin cytoskeleton reorganization (4).

Background: F-box and leucine-rich repeat protein 10 (FBXL10), also known as lysine-specific demethylase 2B (KDM2B) and JmjC domain-containing histone demethylation protein 1B (JHDM1B), is a lysine-specific histone demethylase protein that demethylates Lys4 and Lys36 of histone H3 (1,2). FBXL10 contains a zinc finger-CxxC5 DNA binding domain that binds to un-methylated CpG dinucleotides and has been shown to function as part of a non-canonical polycomb repressor complex (PRC1) that is associated with repression of developmentally regulated genes (3-5). In embryonic stem cells, FBXL10 is critical for targeting PRC1 to CpG islands and regulating gene expression during differentiation. In addition, FBXL10 is over-expressed in various cancers where it functions to induce cell proliferation and repress senescence through repression of the p15Ink4b gene locus (6-8). High expression of FBXL10 in pancreatic ductal adenocarcinoma is associated with metastasis, while high expression in acute myeloid leukemia is associated with increased proliferation and self-renewal of leukemic stem cells (6-8).

Background: Immunity-related GTPase family M protein 1 (IRGM, LRG-47) belongs to the p47 family of immunity related guanosine triphosphatases (IRGs) that regulate innate immune responses to intracellular pathogens (1-3). Research studies indicate that IRGM plays a role in autophagy during clearance of intracellular bacteria (4). Expression of IRGM in mice, but not in humans, is induced by inflammatory signals that include interferon and LPS (2,3). Polymorphisms in the corresponding IRGM gene are associated with some cases of tuberculosis (5-7), Crohn’s disease (8,9), and severe sepsis (10). Additional studies indicate that IRGM functions through regulation of autophagy (4). Mitochondrial IRGM plays a role in mitochondrial fission, membrane polarization, and mitophagy (11). Knockout mice for IRGM show increased susceptibility to infection as well as intestinal inflammation and Paneth cell abnormalities (12,13). Knockout mice against IRGM are also resistant to neuronal autophagy following stroke (14). RNA viruses commonly target IRGM in order to suppress autophagy and enhance infection (15).

Background: Tripartite motif containing protein 27 (TRIM27, RFP) is a member of the tripartite motif (TRIM) family whose members contain a RING domain, a B-box, and a coiled-coil region (together called RBCC). TRIM27 was originally discovered as part of an oncogenic DNA rearrangement resulting in a fusion of the amino terminal RBCC region of TRIM27 with the carboxyl terminal kinase domain of the receptor tyrosine kinase Ret (1). Overexpression of TRIM27 induces JNK and p38 MAPK activation as well as apoptosis (2). TRIM27 has been found to have pleiotropic effects including transcriptional repression (3,4), and E3 ligase activity for ubiquitin (5-7), and SUMO (8). TRIM27 was originally found to interact with Enhancer of Polycomb (EPC) and function as a transcriptional repressor (3). Subsequent studies have identified ubiquitin E3 ligase activity in TRIM27 as well as other members of the TRIM family (reviewed in 9). Potential substrates of TRIM27-mediated ubiquitination include class II PI3K-C2β, NOD2, and WASH. Elevated expression of TRIM27 has been observed in several types of cancer, where in some cases it may be a predictor of poor prognosis (10-13).

Background: Kv4.2 is a voltage-gated potassium channel that belongs to the Shal-related subfamily. Kv4.2 mediates K+ transport in excitable membranes primarily in the brain, where it regulates neuronal excitability, synaptic plasticity, and the circadian rhythm of locomotor activity (1-6). In rodent heart, Kv4.2 mediates the transient outward current (Ito), which contributes to early repolarization and the cardiac action potential (7). Kv4.2 can form homotetramers or heterotetramers with other members of the Shal-related subfamily. Interaction with modulating β subunits such as KChIP family proteins modulates Kv4.2 expression at cell surface and its channel activity (8-10).

Ceramide is an important bioactive lipid triggering signal transduction involved in cell proliferation, apoptosis and differentiation (1,2). A number of SMases have been described and categorized based on their optimum pH activity, cation dependence, tissue distribution, and subcellular localization (1). These include a lysosomal acid SMase, a Zn++-dependent secreted acid SMase, a membrane-bound Mg++-dependent neutral SMase, a Mg++-independent neutral SMase, and an alkaline SMase.

The imbalance of PLP1/DM20, is linked to Pelizaeus-Merzbacher disese (2,3), including mitochonmdrial damage (4). In addition, PLP1, but not DM20, can enter the mitochondria and participate in the metabolism of cells (5, 6).

Background: Activation-induced cytidine deaminase (AID) is thought to modify RNA due to its high homology to the RNA editing enzyme APOBEC-1. This function, however, has not been confirmed in in vitro studies, which show that AID has significant cytidine deaminase activity, and that this activity is blocked by zinc chelation (1).The B cell immune system must specifically recognize several infectious agents, which vastly outnumber immunoglobulin gene segments present in a given organism. Mechanisms such as somatic hypermutation, isotype switch recombination and gene conversion introduce diversity and specificity to the immune system. Analysis of mouse models and patients with AID deficiency has established a link between all three of these mechanisms and AID function (2). AID protein is detected in germinal center centroblast and germinal center derived lymphomas (Burkitt lymphoma), but not in pre-germinal center B cells or post-germinal center neoplasms (B cell chronic lymphocytic leukemia and multiple myeloma) (3).
