Alternative titles and symbols : Platelet glycoprotein iiia; Gp iiia; Platelet fibrinogen receptor, beta subunit; GP3A; CD61;
Description : The ITGB3 gene encodes glycoprotein IIIa (GP IIIa), the beta subunit of the platelet
membrane adhesive protein receptor complex GP IIb/IIIa. The alpha subunit, GP IIb,
is encoded by the ITGA2B gene (607759). The GP IIb/IIIa complex belongs to the integrin
class of cell adhesion molecule receptors that share a common heterodimeric structure
with alpha and beta subunits. Glycoprotein IIIa is also the beta subunit of 2 other
integrins, fibronectin receptor (FNRB; 135630) and vitronectin receptor (193210),
which have distinctive alpha subunits.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutations in the platelet glycoprotein IIIa gene (ITGB3, 173470.0001);
