Purinergic receptor P2Y subtype (P2Y receptor)

P2Y receptors are a family of G protein-coupled receptors activated by extracellular nucleotides (such as ATP, ADP, UTP, and UDP)[3][1][2]. There are eight cloned mammalian P2Y receptor subtypes (P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14), each with distinct tissue distributions, ligand selectivity, and downstream signaling mechanisms[1][3]. P2Y receptors are important regulators of diverse physiological and pathological processes, including vascular tone, platelet aggregation, immune function, and neural activity[2][3][4]. Multiple therapeutics have been developed to exploit or modulate these receptors, especially for cardiovascular and inflammatory disorders[1][3]. "Purinergic receptor P2Y subtype" does not uniquely specify one member or a defined protein, so the specific context or subtype should be identified for biomedical use[3][1].
