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 the primary target for antiplatelet drugs used to prevent thrombosis in cardiovascular diseases. Understanding P2RY12 is essential for maintaining cardiovascular health and managing clotting disorders.
