In the field of molecular biology, the P2Y12 protein is a chemoreceptor for adenosine diphosphate (ADP) and is found on the cell surface of blood platelet cells.[1][2]

The P2Y12 protein belongs to a group of G protein-coupled purinergic receptors[3] and is an important regulator in blood platelet coagulation.[4]

The product of this gene belongs to the family of G-protein coupled receptors. This family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides. This receptor is involved in platelets 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 significanceEdit

The drug clopidogrel binds to this receptor and is marketed as a platelet anticoagulant.[1] In an April 2006 article, a team of researchers published a study of the role of platelet-transported serotonin in liver regeneration in which this method of platelet anticoagulant therapy was used.[6]
