Functioni

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 (By similarity). Required for DOCK10-mediated spine formation in Purkinje cells and hippocampal neurons. Facilitates filopodia formation upon DOCK11-activation (By similarity).By similarity

Enzyme regulationi

Regulated by guanine nucleotide exchange factors (GEFs) which promote the exchange of bound GDP for free GTP, GTPase activating proteins (GAPs) which increase the GTP hydrolysis activity, and GDP dissociation inhibitors which inhibit the dissociation of the nucleotide from the GTPase.By similarity

Interactioni

Subunit structurei

Interacts with CDC42EP1, CDC42EP2, CDC42EP3, CDC42EP4, CDC42EP5, CDC42SE1, CDC42SE2, PARD6A, PARD6B and PARD6G (in a GTP-dependent manner). Interacts with activated CSPG4 and with BAIAP2. Interacts with DOCK11/Zizimin2; the interaction activates CDC42 by exchanging GDP for GTP. Interacts with DOCK9; the interaction activates CDC42 by exchanging GDP for GTP. Interacts with DOCK8 (via DHR-2 domain); the interaction activates CDC42 by exchanging GDP for GTP. Interacts with IQGAP1. Interacts with NET1 and ARHGAP33/TCGAP. Part of a complex with PARD3, PARD6A or PARD6B and PRKCI or PRKCZ. The GTP-bound form interacts with CCPG1. Interacts with USP6. Interacts with NEK6. Part of a collagen stimulated complex involved in cell migration composed of CDC42, CRK, TNK2 and BCAR1/p130cas. Interacts with ITGB1BP1. Interacts with ARHGDIA; this interaction inactivates and stabilizes CDC42. Interacts with ARHGDIB; this maintains CDC42 in the inactive, GDP-bound form. Interacts in (GTP-bound form) with FNBP1L and ABI1, but only in the presence of FNBP1L.By similarity
