Background: Rab27 is a member of the Ras superfamily of small Rab GTPases implicated in exocytosis (1-2). The protein is localized in secretory lysosomes, such as melanosomes in melanocyte or lytic granules in cytotoxic T cells to control exosome secretion pathway (3-5). Rab27 has two isoforms, Rab27a and Rab27b. Rab27a colocalizes with part of CD63 staining vesicles, and Rab27b shows perinuclear distribution. Target knock out studies indicate that the isoforms control different steps of the exosome secretion pathway (6). Rab27a interacts with a wide range of effectors and is involved in multiple steps of exocytosis depending on the effector it associated with and the cell type that is involved (1,2). Rab27a has been shown to be an important player in leukocyte function, cancer metastasis and invasion, and insulin secretion (7-11)

Background: Rab38 is a member of the Rab small G protein family and is mainly expressed in lung alveolar type II cells and melanocytes (1,2). In mice, the G146T Rab38 gene mutation results in loss of Rab38 function and causes abnormal pigmentation due to the loss of melanosomes (3). The Rab38 gene locus has been mapped to oculocutaneous albinism in Ruby rats, a model of human Hermansky-Pudlak Syndrome (4). Analysis of lung structure in the G146T mutation in mice and the Rab38 null mutation in rats also revealed an altered lung surfactant system with enlarged lamellar bodies in type II cells, indicating a role for Rab38 in lung function and development (5,6). Dysfunction mutation studies implicate Rab38 in the post-Golgi trafficking of enzymes (e.g. TYRP1) related to melanogenesis and stability (7,8).

Background: The Rab family of proteins includes small, monomeric GTPases essential for regulating intracellular vesicle trafficking. Members of the Rab3 subfamily, including Rab3A-3D, are involved in the exocytosis of neurotransmitters and hormones (1). Rab3A is primarily expressed in neurons (2), neuroendocrine cells (such as rat PC-12 cells), and in human pancreatic β cells (3,4). By acting as a molecular switch between active GTP-bound Rab3A and the inactive GDP-bound form, Rab3A inhibits synaptic vesicle and chromaffin granule secretion during late membrane release (5,6). Loss-of-function studies suggest Rab3A is involved in controlling synaptic vesicle targeting and docking at the active zone (7). Through binding to its direct effector Rabphillin, Rab3A also orchestrates the coupling between synaptic vesicle exocytosis and endocytosis (8).

Background: Rab5 is a member of the Ras superfamily of small Rab GTPases. Rab5 is localized at the plasma membrane and early endosomes and functions as a key regulator of vesicular trafficking during early endocytosis (1). The conformational change between Rab5 GTP/GDP states is essential for its biological function as a rate limiting regulator at multiple steps during endocytosis (1,2). Rab5 exerts its function by interacting with several Rab5-specific effectors (1-3). These proteins form complexes with Rab5 on a specialized Rab domain of the endosome and promote recycling of Rab5-cargo targets between endosome and the plasma membrane.

Background: Rab6 is a member of the Ras superfamily of small Rab GTPases implicated in endocytosis (1). The three distinct members of the Rab6 subfamily (Rab6A, Rab6A', and Rab6B) are structurally similar but likely exhibit non-overlapping functions (2,3). Rab6 localized to the Golgi (4) regulates retrograde transport of membrane-bound target proteins from the Golgi apparatus to the endoplasmic reticulum (5-7) or from the Golgi to the endosome during exocytotic transport (8). Rab6 interacts with microtubule motor proteins such as rabkinesin-6 (KIF20A) and dynein/dynactin complexes; Rab6-mediated transport requires a functionally intact microtubule system (9,10). Rab6 also regulates cytokinesis and cell cycle check point through interactions with Rab6 effector proteins, including the dynein/dynactin protein DCTN1 and the GTPase activating protein RABGAP1 (11,12).

Background: Rab7 and Rab9 are members of the Ras superfamily of small Rab GTPases (1). Both proteins are located in late endosomes, but exert different functions. Rab7 associates with the RIPL effector protein to control membrane trafficking from early to late endosome and to lysosomes (2,3). Rab7 also helps to regulate growth receptor endocytic trafficking and degradation (3,4), and maturation of phagosome and autophagic vacuoles (4-6). Rab9 interacts with its effector proteins p40 and TIP47 (7,8) to promote the MPR (mannose 6-phosphate receptor)-associated lysosomal enzyme transport between late endosomes and the trans Golgi network (9,10).

Background: The Rab8 GTPase is a member of the Ras superfamily that functions in protein transport and membrane restructuring (1). Studies show that Rab8 is localized to the trans Golgi network (TGN), basolateral membrane, and vesicular structures where it helps regulate target protein transport between TGN and the basolateral membrane (1-3). Overexpression studies and mutation analysis of Rab8 and its associated Rab8GEF indicate additional roles in actin and microtubule remodeling during polarized membrane transport and membrane protrusion formation (4-6). Rab8 associates with myosin Vb and is required for translocation of GLUT4 following insulin stimulation in muscle (7,8). Control of target protein vesicle transport by Rab8 also regulates MT1-MMP activity during extracellular matrix formation and JRAB/MICAL-L2 at tight junction formation (9,10).

Background: Rabex-5, also called RabGEF1 and RAP1, was identified as a guanine nucleotide exchange factor (GEF) for Rab5, a member of the Ras superfamily of small Rab GTPases (1). Rabex-5 generates the GTP-bound active form of Rab5 and forms a tight association with its effector protein Rabaptin-5 (2). This complex localizes to endosomal membranes where it functions as a key regulator of vesicular trafficking during early endocytosis (3,4). Rabex-5 is also monoubiquitinated and has ubiquitin ligase activity that regulates its recruitment to early endosomes (5,6). The conformational change between Rab5 GTP/GDP states is essential for its biological function as a rate limiting regulator at multiple steps during endocytosis (5). Through its control of endosomal trafficking and endocytosis, Rabex-5 has been shown to negatively regulate NGF-mediated neurite outgrowth (7) as well as FcεRI-dependent mast cell activation (8).

Background: The highly conserved receptor for activated C kinase 1 (RACK1), homologous to the β subunit of heterotrimeric G-proteins, was originally identified through its binding of active PKCβII and other classical PKC isoforms (1). RACK1 is a scaffold protein that recruits PKC and a wide range of other proteins to specific subcellular locations, promoting the formation of multiprotein complexes to induce and integrate various signaling pathways (reviewed in 2). One example of this is its enhancement of PKC-dependent JNK activation (3). RACK1 protein also resides in the eukaryotic ribosome, suggesting the possibility that RACK1 participates in the assembly of signaling complexes that regulate translation as well (reviewed in 4). RACK1 binds the SH2 domain of Src, and phosphorylation of RACK1 by Src occurs at Tyr228 after PKC activation (5).

Background: The human checkpoint protein Rad17 and its fission and budding yeast orthologues (Schizosaccharomyces pombe Rad17 and Saccharomyces cerevisiae Rad24, respectively) are involved in the activation of checkpoint signals in response to DNA damage or disruption of DNA synthesis (1-4). Treatment of human cells with genotoxic agents induces ATM/ATR-dependent phosphorylation of Rad17 at Ser635 and Ser645. Rad17 phosphorylation is a critical early event during checkpoint signaling in DNA-damaged cells (5-7).

Background: DNA damage, if not repaired, can lead to genome instability and tumorigenesis. Eukaryotic cells use multiple (sometimes overlapping) signaling pathways to respond to agents that cause various types of DNA lesions. Downstream molecules in DNA repair pathways converge on the sites of DNA damage, resulting in cell cycle arrest and repair or apoptosis (1). Rad18 is an E3 ubiquitin ligase recruited to sites of DNA damage. Along with the E2 ubiquitin ligase Rad6, Rad18 is responsible for monoubiquitination of DNA damage proteins including the replication clamp PCNA and the Fanconi anemia core protein FANCD2. Monoubiquitination of these proteins signals to downstream effector molecules and results in the repair of either post-replication repair lesions via the translesion synthesis (TLS) pathway or DNA double strand breaks via homologous recombination (2-4). Phospho-proteomic studies indicate that Ser403 of Rad18 may be phosphorylated by ATM/ATR in response to DNA damage-inducing agents (5,6).

Application Methods: Immunoprecipitation, Western Blotting

Background: The cohesin complex consists of a heterodimer between SMC1 (SMC1A or B) and SMC3, bound by additional RAD21 and STAG proteins (STAG1, 2, or 3) (1,2). These proteins form a ring-like structure that mediates the cohesion of two sister chromatids after DNA replication in S phase (1,2). RAD21 and STAG2 are phosphorylated by Polo-like kinase (PLK) during prophase, which leads to the dissociation of cohesin complexes from the chromosome arms; however, cohesin remains bound to centromeres until anaphase (3,4). RAD21 is cleaved by separin/ESPL1 in anaphase, which leads to dissociation of the remaining cohesin from centromeres, enabling sister chromatids to segregate during mitosis (5). RAD21 is also cleaved by caspase-3 and caspase-7 during apoptosis, resulting in a 64 kDa carboxy-terminal cleavage product that translocates to the cytoplasm and may help to trigger apoptosis (6,7). In addition to mediating cohesion of sister chromatids, the cohesin complex plays important roles in gene regulation and DNA repair, as SMC1 and SMC3 are both phosphorylated by ATM and ATR kinases upon DNA damage (1,2).
