Background: The prostaglandin D2 receptor DP1 (DP or PTGDR) is a G protein- coupled receptor for the prostaglandin D2 (PGD2). PGD2 signals through DP2 (CRTH2) to induce TH2, eosinophil, and basophil chemotaxis in a Gαi-dependent manner. In contrast, signaling through DP1 is coupled to Gαs and does not induce chemotaxis.
Application: Functional assays
