[Activated p21cdc42Hs Kinase, encoded by the ACK1 gene, is a non-receptor tyrosine kinase. It binds CDC42 in its GTP-bound activated form and inhibits both the intrinsic and GTPase-activating protein (GAP)-stimulated GTPase activity of CDC42. This binding is mediated by a unique sequence of 47 amino acids C-terminal to an SH3 domain. The encoded protein may be involved in a regulatory mechanism that sustains the GTP-bound active form of CDC42 and which is directly linked to a tyrosine phosphorylation signal transduction pathway.
