About IQGAP1

Cytogenetic location: 15q26.1 Genomic coordinates (GRCh38): 15:90,388,242-90,502,239 (from NCBI)

This gene has 18 transcripts (splice variants), 217 orthologues and 2 paralogues. Ubiquitous expression in colon (RPKM 49.8), appendix (RPKM 48.4) and 25 other tissues.

Summary

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]
