IQGAP2
gene geneOn this page
Summary
IQGAP2 (IQ motif containing GTPase activating protein 2, HGNC:6111) is a protein-coding gene on chromosome 5q13.3, encoding Ras GTPase-activating-like protein IQGAP2 (Q13576). Binds to activated CDC42 and RAC1 but does not seem to stimulate their GTPase activity.
This gene encodes a member of the IQGAP family. The encoded protein contains three IQ domains, one calponin homology domain, one Ras-GAP domain and one WW domain. This protein interacts with components of the cytoskeleton, with cell adhesion molecules, and with several signaling molecules to regulate cell morphology and motility. It also acts as a tumor suppressor and has been found to play a role in regulating innate antiviral responses. Alternative splicing results in multiple transcript variants.

Literature-anchored findings (GeneRIF, showing 22)
- The gene for the putative rac1/cdc42 effector protein IQGAP2 was found in the PAR gene cluster at 5q13, flanked by PAR1 & encompassing PAR3. It functions as a GTP-dependent effector protein in thrombin-induced platelet cytoskeletal reorganization. (PMID:12515716)
- silencing of IQGAP2 by promoter methylation may contribute to gastric cancer development. (PMID:17957782)
- The top-ranked SNP, rs457717 for association with age-related hearing impairment(P-value 3.55 x 10(-7)), was localised in an intron of the IQ motif-containing GTPase-activating-like protein (IQGAP2). (PMID:20068591)
- increased IQGAP1 and/or decreased IQGAP2 contribute to the pathogenesis of human HCC. (PMID:20977743)
- The first IQ-motifs from IQGAP2 and IQGAP3 form transient interactions with calmodulin in the absence of calcium. (PMID:21299499)
- observations strongly indicate that IQGAP2 is a surveillance type of tumour suppressor for prostate cancer (PMID:22406297)
- Low IQGAP2 expression was associated with hepatocellular carcinoma. (PMID:24998570)
- Mammalian IQGAP proteins may play a role in cytokinesis by regulating the localization of key cytokinesis regulatory proteins to the contractile apparatus during mitosis. (PMID:25229330)
- IQGAP1, IQGAP2, and IQGAP3 have diverse roles in vertebrate physiology, operating in the kidney, nervous system, cardiovascular system, pancreas, and lung. (Review) (PMID:25722290)
- Data show that IQ motif-containing GTPase-activating protein 2 (IQGAP2) expression is altered in colitis. (PMID:26047140)
- we identified IQGAP2 as a human and zebrafish podocyte gene product that is downregulated in microarray data sets from kidney biopsies of human patients with focal segmental glomerulosclerosis and minimal change nephrotic syndrome. (PMID:26154927)
- IQGAP2 TagSNP rs457717 (A/G) was not associated with Age-Related Hearing impairment in Han male Chinese population. (PMID:26187738)
- Thus, these data identified IQGAP2 as a novel tumor suppressor for ovarian cancer to inhibit cell invasion through regulating Wnt/b-catenin signaling, and provided a new biomarker and potential therapeutic strategy for this disease. (PMID:26549344)
- The most frequently identified and connected to preterm birth genes in the exome library were IGF1, ATM and IQGAP2. (PMID:27163930)
- The structural basis for Cdc42-induced dimerization of IQGAP1 and IQGAP2 has been uncovered. (PMID:27524202)
- IQGAP2 expression correlated positively with survivability, on the contrary, IQGAP3 expression levels correlated inversely with survivability (PMID:29073199)
- Data suggest that CDC42 binding to Ex-domain of IQGAP2 releases Ex-domain at C-terminal region of GRD2 domain, facilitating IQGAP2 dimerization; this promotes allosteric changes in ras GTPase-activating protein binding site providing binding site for second CDC42; RAC1 binds only to apo-IQGAP2. (IQGAP2 = IQ motif containing GTPase activating protein-2; CDC42 = GTP-binding protein CDC42; RAC1 = Rac family small GTPase-1) (PMID:29358323)

- Reduced IQGAP2 expression promotes EMT and inhibits apoptosis by modulating the MEK-ERK and p38 signaling in breast cancer irrespective of ER status. (PMID:33846302)
- IQGAP2 acts as an independent prognostic factor and is related to immunosuppression in DLBCL. (PMID:34034707)

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 122 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
