Protein Name: Ras GTPase-activating-like protein IQGAP1

UniprotKB/SwissProt ID: IQGA1_HUMAN (P46940)

Gene Name: IQGAP1

Synonyms: KIAA0051

Organism: Homo sapiens (Human).

Function: Binds to activated CDC42 but does not stimulate its GTPase activity. It associates with calmodulin. Could serve as an assembly scaffold for the organization of a multimolecular complex that would interface incoming signals to the reorganization of the actin cytoskeleton at the plasma membrane. May promote neurite outgrowth.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cell membrane.
