Summary
This gene encodes a G-protein-coupled receptor that is preferentially expressed in CD4+ effector T helper 2 (Th2) cells. This protein is a prostaglandin D2 receptor that mediates the pro-inflammatory chemotaxis of eosinophils, basophils, and Th2 lymphocytes generated during allergic inflammation. Single nucleotide polymorphisms in the 3' UTR of this gene have been associated with asthma susceptibility.[provided by RefSeq, Mar 2011]

Comments
| Comment Type | Description |
|---|---|
| Domain | The 330-DSEL-333 motif is involved in the recycling of PTGDR2 to the cell surface after agonist-induced internalization. This motif seems to be required for ADRBK1/GRK2 and GPRK5/GRK5 to promote agonist-induced internalization. Thr-347 is a major site for PKC-induced internalization of the receptor. |
| 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. {ECO:0000269|PubMed:11208866, ECO:0000269|PubMed:11535533, ECO:0000269|PubMed:17196174}. |
