Members of Rho family are small G proteins that transduce signals from plasma-membrane receptors and control cell adhesion, motility and shape by actin cytoskeleton formation. Like all other GTPases, Rho proteins act as molecular switches, with an active GTP-bound form and an inactive GDP-bound form. The active conformation is promoted by guanine-nucleotide exchange factors, and the inactive state by GTPase-activating proteins (GAPs), which stimulate the intrinsic GTPase activity of small G proteins.This entry represents Rho GTPase activating protein 27 (ARHGAP27, also known as CIN85-associated multi-domain-containing Rho GTPase-activating protein 1, CAMGAP1), a binding protein for Cbl-interacting protein of 85kDa (CIN85), an adaptor protein involved in the endocytic process of several receptor tyrosine kinases. It also has activity towards Rac1 and Cdc42 [].
