Integrin Alpha IIb / CD41 (ITGA2B) Antibody

Background

ITGA2B, also known as integrin alpha 2b or CD41, is a transmembrane glycoprotein that plays a central role in platelet adhesion and aggregation. It is primarily expressed on platelets and megakaryocytes. Together with integrin beta 3 (ITGB3), ITGA2B forms the αIIbβ3 integrin complex (also known as GPIIb/IIIa), which is the most abundant integrin on the surface of platelets and is crucial for blood clot formation (hemostasis). This receptor mediates platelet aggregation by binding to fibrinogen, von Willebrand factor (vWF), fibronectin, and other adhesive proteins during platelet activation. When platelets are stimulated, the αIIbβ3 complex undergoes a conformational change that allows it to bind its ligands and mediate platelet-platelet interactions.
