Protein

Prostaglandin D2 receptor 2

Gene

PTGDR2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Receptor for prostaglandin D2 (PGD2). Coupled to the G(i)-protein. Receptor activation may result in pertussis toxin-sensitive decreases in cAMP levels and Ca2+ 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.3 Publications

Motifi330 – 3334Involved in the recycling of CRTH2

Domaini

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.
