In the field of
purinergic signaling, the P2Y 12 protein is found mainly but not exclusively on the surface of blood platelets, and is an important regulator in blood clotting. [1 ]
12 belongs to the Gi class of a group of G protein-coupled (GPCR) purinergic receptors and is a [2 ] chemoreceptor for adenosine diphosphate (ADP). [3 ] The P2Y family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various [4 ] adenosine and uridine nucleotides. This receptor is involved in platelet aggregation, and is a potential target for the treatment of thromboembolisms and other clotting disorders. Two transcript variants encoding the same isoform have been identified for this gene. [5 ]
Clinical significance [ edit ]
clopidogrel (PLAVIX), prasugrel (Efient, Effient) and ticagrelor (BRILINTA) bind to this receptor and are marketed as antiplatelet agents. [3 ]
