The P2Y receptors belong to the G-protein coupled receptor superfamily. They mediate the actions of the extracellular nucleotides (ATP, ADP, UTP and UDPA). Eight functional mammalian P2Y receptors have been described: P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and the UDP-glucose receptor, now renamed P2Y14.1-3
The P2Y12 receptor is co-expressed with P2Y1 receptor on platelets leading to shape change, aggregation, and rise in intracellular Ca2+ upon activation.
The only other expression of P2Y12 was found in brain, according to results of reverse transcription-polymerase chain reaction and northern blotting.4 The P2Y12 receptor has become a target for potential therapeutic drugs for the treatment of thromboembolism and other clotting disorders.4
Expression of P2Y12 receptor in human eosinophils.A. Indirect flow cytometry of human eosinophils using Anti-P2Y12 Receptor Antibody (#APR-012). B. Immunocytochemical staining of human eosinophils using Anti-P2Y12 Receptor Antibody. P2Y12 immunostaining is shown in green. In both applications, preincubating the antibody with the blocking peptide abolishes the detection of the receptor.Adapted from Muniz, V.S. et al.
