General annotation (Comments)

Function	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. Causes the formation of thin, actin-rich surface projections called filopodia.
Enzyme regulation	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.
Subunit structure	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 Zizimin1/DOCK9 and Zizimin2/DOCK11, which activate it by exchanging GDP for GTP. Interacts with NET1 and TCGAP/SNX26. Part of a complex with PARD3, PARD6A or PARD6B and PRKCI or PRKCZ. The GTP-bound form interacts with CCPG1. Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 Ref.14
Subcellular location	Cell membrane; Lipid-anchor; Cytoplasmic side Potential.
Sequence similarities	Belongs to the small GTPase superfamily. Rho family. CDC42 subfamily.
