Protein Structure
UniProt Annotation
Function Receptor for prostaglandin D2 (PGD2). Coupled to the G(i)-protein. Receptor activation may result in pertussis toxin- sensitive decreases in cAMP levels and Ca(2+) mobilization. PI3K signaling is also implicated in mediating PTGDR2 effects. PGD2 induced receptor internalization. CRTH2 internalization can be regulated by diverse kinases such as, PKC, PKA, ADRBK1/GRK2, GPRK5/GRK5 and GRK6. Receptor activation is responsible, at least in part, in immune regulation and allergic/inflammation responses (By similarity). {ECO:0000250}.
Subcellular Localization Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Note=Internalized receptors colocalized with RAB11A. {ECO:0000250}.
