ITGB3(redirected from integrin, beta 3)
ITGB3A gene on chromosome 17q25 that encodes an integrin beta chain protein (integrins are noncovalently associated transmembrane glycoprotein receptors, composed one of 18 different alpha and one of 8 different beta chains). The beta-3 chain partners with the alpha-IIb chain and acts as a receptor for fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin, vitronectin and platelets. Beta-3 chain partnered with the alpha-5 chain is a receptor for cytotactin, fibronectin, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, vitronectin and von Willebrand factor.
