P2Y10 belongs to the family of G-protein coupled receptors (GPCRs) and was first described as a lymphoid-restricted receptor. Based on sequence homology, it was thought to be a member of the purinergic P2Y GPCR family and a nucleotide receptor 1. Later studies suggested that it was a receptor for lysophosphatidic acid (LPA) and sphingosine-1-phosphate (S1P)2, although the findings were not confirmed by others.
More recent studies using a TGFα shedding assay, showed P2Y10 as a receptor for lysophosphatidylserine (LysoPS), a bioactive lipid present in the central nervous system (CNS) and immune system 3,4. Nevertheless, P2Y10 is still classified by the International Union of Basic and Clinical Pharmacology, as an orphan class A GPCR receptor.
P2Y10 putative ligand, LysoPS, has been found to activate at least two other class A orphan GPCRs named GPR34 and GPR174, that have also been named as LYPSR1 and LYPSR3 (respectively), with P2Y10 also named as LYPSR24.
The biological function of P2Y10 has not been completely elucidated, but different studies point to a role in eosinophil degranulation5, involvement in neuroinflammation6 and regulation of T-cell migration7.
Anti-P2Y10 (extracellular) Antibody (#APR-110) is a highly specific antibody directed against an extracellular epitope of the mouse protein. The antibody can be used in western blot, immunohistochemistry and flow cytometry applications. It has been designed to recognize P2Y10 from mouse and rat samples. The antibody is unlikely to recognize human P2Y10.
