Overview
IQGAP2 Binds to activated CDC42 and RAC1 but does not seem to stimulate their GTPase activity. Associates with calmodulin. Isoform 2 expression is enhanced in testis. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: G protein regulator, misc.; Motility/polarity/chemotaxis
Cellular Component: microtubule; microvillus; actin cytoskeleton
Molecular Function: calmodulin binding; phosphatidylinositol-3,4,5-triphosphate binding; actin binding; Ras GTPase activator activity; GTPase inhibitor activity
Biological Process: small GTPase mediated signal transduction; negative regulation of catalytic activity; signal transduction
Reference #:  Q13576 (UniProtKB)
Alt. Names/Synonyms: IQ motif containing GTPase activating protein 2; IQGA2; IQGAP2; Ras GTPase-activating-like protein IQGAP2
Gene Symbols: IQGAP2
Molecular weight: 180,578 Da
Basal Isoelectric point: 5.47  Predict pI for various phosphorylation states
CST Pathways:  Adherens Junction Dynamics
