      DescriptionRac1/Cdc42 Activation Assay Kit
      OverviewThe Rac1/Cdc42 Activation Assay (Cat. No. 17-441) provides an effective method for detecting Rac and Cdc42 activity in cell lysates. This assay uses the downstream effector of Rac/Cdc42, p21-activated protein kinase (PAK1), to isolated the active GTP-bound form of Rac/Cdc42 from the sample. The p21 binding domain (PBD) of PAK1 is expressed as a GST-fusion protein and coupled to agarose beads. After precipitation, an immunoblot is performed and the activated Rac/Cdc42 is detected with specific monoclonal antibodies, followed by HRP-conjugated secondary antibody and ECL reagent.

      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.

      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.
      Product Usage Statements
      Quality AssuranceRoutinely evaluated by precipitating Rac1-GTP and cdc42-GTP from 3T3/A31 and HeLa cell lysates that had been loaded with GTPγS(lysates were loaded in vitro with GTPγS for cdc42-GTP). The precipitated Rac1-GTP and cdc42-GTP was detected by immunoblot analysis using anti-Rac1 (1 μg/ml).
