      DescriptionAnti-Rac1b Antibody
      Background InformationRac is a member of the Rho family of small GTP-binding proteins. It plays roles in cytoskeletal actin organization as well as transformation along with its other Rho family members. Rac, Rho, and Cdc42 all work in concert with one another in the assembly of actin-based structures such as lamellipodia, stress fibers, and filopodia, respectively to control cell migration. Rac is activated downstream of cdc42, or independently by Ras signaling, and in turn Rac stimulates Rho. Effectors of the Rac pathway include NADPH Oxidase and the SAPK1/JNK family of kinases. The latter pathway is activated by the PAK kinases, which are direct targets of Rac.
      Rac1b is a highly active splice varient of Rac1. It differs in that it has an additional 19 amino acids. It has been found in various tumors such as breasts and colorectal.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq]
      Transcript Variant: This variant (Rac1b) includes the alternatively spliced 57 bp region (exon 3b) that is missing in transcript variant Rac1.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P63000 # Isoform B has an accelerated GEF-independent GDP/GTP exchange and an impaired GTP hydrolysis, which is restored partially by GTPase-activating proteins. It is able to bind to the GTPase-binding domain of PAK but not full-length PAK in a GTP- dependent manner, suggesting that the insertion does not completely abolish effector interaction.
      SIZE: 192 amino acids; 21450 Da
      SUBUNIT: Interacts with the GEF proteins PREX1, RASGRF2, DOCK1, DOCK2 and DOCK7, which promote the exchange between GDP and GTP, and therefore activate it. Interacts with PARD6A, PARD6B and PARD6G in a GTP-dependent manner. Part of a quaternary complex containing PARD3, some PARD6 protein (PARD6A, PARD6B or PARD6G) and some atypical PKC protein (PRKCI or PRKCZ), which plays a central role in epithelial cell polarization. Found in a trimeric complex composed of DOCK1 and ELMO1, which plays a central role in phagocytosis of apoptotic cells. Interacts with RALBP1 via its effector domain. Interacts with PLXNB1. Part of a complex with MAP2K3, MAP3K3, CCM2 and DEF6. Interacts with BAIAP2, CYFIP1/SRA-1 and DEF6. Interacts with Y.pseudotuberculosis YPKA and PLCB2.
      SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor; Cytoplasmic side (By similarity). Melanosome. Note=Inner surface of plasma membrane possibly with attachment requiring prenylation of the C- terminal cysteine (By similarity). Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
      TISSUE SPECIFICITY: Isoform B is predominantly identified in skin and epithelial tissues from the intestinal tract. The expression of isoform B is elevated in colorectal tumors at various stages of neoplastic progression, as compared to their respective adjacent tissues.
      DOMAIN: SwissProt: P63000 The effector region mediates interaction with DEF6.
      SIMILARITY: Belongs to the small GTPase superfamily. Rho family.
