CDC42 (P60953) - Overview - Molecular Target Synopsis


CDC42, Cell division control protein 42 homolog
UniProt P60953

Also Known as CDC42_HUMAN, CDC42

Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Regulates the bipolar attachment of spindle microtubules to kinetochores before chromosome congression in metaphase. Plays a role in the extension and maintenance of the formation of thin, actin-rich surface projections called filopodia. Mediates CDC42-dependent cell migration. Required for DOCK10-mediated spine formation in Purkinje cells and hippocampal neurons. Facilitates filopodia formation upon DOCK11-activation (By similarity). Also plays a role in phagocytosis through organization of the F-actin cytoskeleton associated with forming phagocytic cups. Interacts with CDC42EP1, CDC42EP2, CDC42EP3, CDC42EP4, CDC42EP5, CDC42SE1, CDC42SE2, PARD6A, PARD6B and PARD6G (in a GTP-dependent manner) (PubMed:10490598, PubMed:10816584, PubMed:10954424, PubMed:11260256). Interacts with activated CSPG4 and with BAIAP2 (PubMed:10587647, PubMed:11130076). Interacts with activated CSPG4 and with BAIAP2 (By similarity). Interacts with DOCK11/Zizimin2; the interaction activates CDC42 by exchanging GDP for GTP (By similarity). Interacts with DOCK9; the interaction activates CDC42 by exchanging GDP for GTP (PubMed:12172552, PubMed:19745154). Interacts with DOCK8 (via DHR-2 domain); the interaction activates CDC42 by exchanging GDP for GTP (PubMed:12172552). Interacts with IQGAP1 (By similarity). Interacts with NET1 and ARHGAP33/TCGAP (By similarity). Part of a complex with PARD3, PARD6A or PARD6B and PRKCI or PRKCZ (PubMed:11260256). The GTP-bound form interacts with CCPG1 (By similarity). Interacts with USP6 (PubMed:12612085). Interacts with NEK6 (PubMed:20873783). Part of a collagen stimulated complex involved in cell migration composed of CDC42, CRK, TNK2 and BCAR1/p130cas (PubMed:17038317). Interacts with ITGB1BP1 (PubMed:11807099). Interacts with ARHGDIA; this interaction inactivates and stabilizes CDC42 (PubMed:23434736). Interacts with ARHGDIB; this maintains CDC42 in the inactive, GDP-bound form (PubMed:7512369). Interacts (in GTP-bound form) with FNBP1L and ABI1, but only in the presence of FNBP1L (PubMed:19798448). May interact with ARHGEF16; responsible for the activation of CDC42 by the viral protein HPV16 E6 (PubMed:21139582).
