DESCRIPTION

Also known as ITA2B_HUMAN, ITGA2B, GP2B, ITGAB. Integrin alpha-IIb/beta-3 is a receptor for fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin. It recognizes the sequence R-G-D in a wide array of ligands. It 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 cell surface. Heterodimer of an alpha and a beta subunit. The alpha subunit is composed of a heavy and a light chain linked by a disulfide bond. Alpha-IIb associates with beta-3. Directly interacts with RNF181. Interacts (via C-terminus cytoplasmic tail region) with CIB1; the interaction is direct and calcium-dependent. Interacts (via C-terminus cytoplasmic tail region) with CIB2, CIB3 and CIB4; the interactions are stabilized/increased in a calcium and magnesium-dependent manner. ITGA2B:ITGB3 interacts with PPIA/CYPA; the interaction is ROS and PPIase activity-dependent and is increased in the presence of thrombin (By similarity).
