Prostaglandin D2 receptor 2 (DP2) is a human protein encoded by the PTGDR2 gene.[4] DP2 has also been designated as CD294 (cluster of differentiation 294).


G protein-coupled receptors (GPCRs), such as DP2, are integral membrane proteins containing 7 putative transmembrane domains (TMs). These proteins mediate signals to the interior of the cell via activation of heterotrimeric G proteins that in turn activate various effector proteins, ultimately resulting in a physiologic response.[supplied by OMIM][4]

DP2 has recently been found when activated by elevated level of prostaglandin D2 (PGD2), it could inhibit hair growth. This suggests the DP2 pathway as a potential target for bald treatment.[5] A particularly promising compound for blocking the DP2 pathway is a compound known as TM30089, which exhibits a "functional insurmountability" of PGD2 expression.[6]
