P2RY12 (Purinergic Receptor P2Y12): P2RY12 is a receptor for adenosine diphosphate (ADP) that plays a crucial role in platelet aggregation — a vital process in blood clot formation. It is a primary target for antiplatelet medications used to prevent thrombosis in cardiovascular diseases. Understanding P2RY12 is essential for maintaining cardiovascular health and managing clotting disorders.
