Summaries for IQGAP1 Gene

Entrez Gene Summary 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]

GeneCards Summary for IQGAP1 Gene

IQGAP1 (IQ Motif Containing GTPase Activating Protein 1) is a Protein Coding gene. Diseases associated with IQGAP1 include Bullous Skin Disease and Wolf-Hirschhorn Syndrome. Among its related pathways are RET signaling and Oncogenic MAPK signaling. 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

  • 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.

UniProtKB/Swiss-Prot:

IQGA1_HUMAN :
  • Regions C1 and C2 can either interact with nucleotide-free CDC42, or interact together, depending on the phosphorylation state of Ser-1443. When Ser-1443 is not phosphorylated, C1 and C2 interact, which prevents binding of nucleotide-free CDC42 and promotes binding of GTP-bound CDC42. Phosphorylation of Ser-1443 prevents interaction between C1 and C2, which opens the structure of the C-terminus and allows binding and sequestration of nucleotide-free CDC42 on both C1 and C2.
