Primary gene name(s)ITGAV
Synonym gene name(s)MSK8, VNRA
Protein nameIntegrin alpha-V
Protein functionThe alpha-V, ITGAV integrins are receptors for vitronectin, cytotactin, fibronectin, fibrinogen, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin and vWF. They recognize the sequence R-G-D in a wide array of ligands. ITGAV:ITGB3 binds to fractalkine, CX3CL1 and may act as its coreceptor in CX3CR1-dependent fractalkine signaling, PubMed:23125415. ITGAV:ITGB3 binds to NRG1, via EGF domain and this binding is essential for NRG1-ERBB signaling, PubMed:20682778. ITGAV:ITGB3 binds to FGF1 and this binding is essential for FGF1 signaling, PubMed:18441324. ITGAV:ITGB3 binds to IGF1 and this binding is essential for IGF1 signaling, PubMed:19578119. ITGAV:ITGB3 binds to PLA2G2A via a site, site 2 which is distinct from the classical ligand-binding site, site 1 and this induces integrin conformational changes and enhanced ligand binding to site 1, PubMed:18635536, PubMed:25398877. ITGAV:ITGB3 and ITGAV:ITGB6 act as a receptor for fibrillin-1, FBN1 and mediate R-G-D-dependent cell adhesion to FBN1, PubMed:12807887, PubMed:17158881. {ECO:0000269|PubMed:12807887, ECO:0000269|PubMed:17158881, ECO:0000269|PubMed:18441324, ECO:0000269|PubMed:18635536, ECO:0000269|PubMed:19578119, ECO:0000269|PubMed:20682778, ECO:0000269|PubMed:23125415, ECO:0000269|PubMed:25398877}.; FUNCTION:, Microbial infection Integrin ITGAV:ITGB5 acts as a receptor for adenovirus type C, PubMed:20615244.

Integrin ITGAV:ITGB3 acts as a receptor for Human parechovirus 1, PubMed:11160695. Integrin ITGAV:ITGB3 acts as a receptor for West nile virus, PubMed:23658209.
