Previous GeneCards Identifiers for IQGAP1 Gene
This gene encodes a member of the IQGAP family. The protein contains four IQ domains, one calponin homology domain, one Ras-GAP domain and one WW domain. It interacts with components of the cytoskeleton, with cell adhesion molecules, and with several signaling molecules to regulate cell morphology and motility. Expression of the protein is upregulated by gene amplification in two gastric cancer cell lines. [provided by RefSeq, Jul 2008]

Among its related pathways are Signaling by moderate kinase activity BRAF mutants and EGF/EGFR Signaling Pathway. Gene Ontology (GO) annotations related to this gene include calcium ion binding and GTPase activator activity. An important paralog of this gene is IQGAP3.
UniProtKB/Swiss-Prot for IQGAP1 Gene
Plays a crucial role in regulating the dynamics and assembly of the actin cytoskeleton. 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 (PubMed:15695813). May play a possible role in cell cycle regulation by contributing to cell cycle progression after DNA replication arrest (PubMed:20883816).
