Overview

Integrin alpha-V/beta-3 (ITGAV:ITGB3) is a receptor for cytotactin, fibronectin, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, vitronectin and von Willebrand factor. Integrin alpha-IIb/beta-3 (ITGA2B:ITGB3) is a receptor for fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin. Integrins alpha-IIb/beta-3 and alpha-V/beta-3 recognize the sequence R-G-D in a wide array of ligands. Integrin alpha-IIb/beta-3 recognizes the sequence H-H-L-G-G-G-A-K-Q-A-G-D-V in fibrinogen gamma chain. Following activation integrin alpha-IIb/beta-3 brings about platelet/platelet interaction through binding of soluble fibrinogen. This step leads to rapid platelet aggregation which physically plugs ruptured endothelial surface. Fibrinogen binding enhances SELP expression in activated platelets (By similarity). In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi"s sarcoma lesions.

Molecular Function

Cell adhesion, Host-virus interaction

Subcellular Location

Cell junction, Cell membrane, Cell projection, Membrane

Expression

Isoform beta-3A and isoform beta-3C are widely expressed. Isoform beta-3A is specifically expressed in osteoblast cells; isoform beta-3C is specifically expressed in prostate and testis.

Structure

Heterodimer of an alpha and a beta subunit. Beta-3 (ITGB3) associates with either alpha-IIb (ITGA2B) or alpha-V (ITGAV). Isoform Beta-3C interacts with FLNB. Interacts with COMP. Interacts with PDIA6 following platelet stimulation. Interacts with SYK; upon activation by ITGB3 promotes platelet adhesion. Interacts with MYO10. Interacts with DAB3. Interacts with FERMT2. Interacts with EMP2; regulates the levels of the heterodimer ITGA5:ITGB3 integrin expression on the plasma membrane (PubMed:16216233). Integrin ITGAV:ITGB3 interacts with FBLN5 (via N-terminus). Integrin ITGAV:ITGB3 interacts with herpes virus 8/HHV-8 glycoprotein B and acts as a receptor for the virus. Interacts with HIV-1 Tat.
