ITGB3

A 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.

Some experts have demonstrated that genetic polymorphisms of platelet membrane glycoproteins (GPI1, GPIba, GPIIIa, and GPIV) may influence the efficacy of aspirin or platelet responsiveness, and genetic polymorphisms of the thromboxane A2 receptor (TBXA2R), platelet-activating factor acetylhydrolase, and coagulation factor XIII were associated with platelet aggregation.
Thrombocytopenia is a common problem in HIV owing to cross-reactivity of antibodies to HIV with glycoprotein GPIIb and/ or GPIIIa on the platelet surface or talin within the platelet cytoskeleton.
