UniProtKB - Q9Z2J6 (PD2R2_MOUSE)
Protein
Prostaglandin D2 receptor 2
Gene
Ptgdr2
Organism
Mus musculus (Mouse)
Status
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, GRK2, GPRK5/GRK5 and GRK6. Receptor activation is responsible, at least in part, in immune regulation and allergic/inflammation responses (By similarity).

Disruption phenotypei
Deficient mice are fertile and grew normally. Ear-swelling responses induced by hapten-specific IgE are less pronounced in deficient mice, giving 35-55% of the responses of normal mice. The reduction in cutaneous responses is associated with decreased infiltration of lymphocytes, eosinophils, and basophils and decreased production of macrophage-derived chemokine and RANTES at inflammatory sites. In models of chronic contact hypersensitivity induced by repeated hapten application, CRTH2-deficient mice result in a reduction by approximately half of skin responses and low levels (63% of control) of serum IgE production.1 Publication

Domaini
The 329-DSEL-332 motif is involved in the recycling of PTGDR2 to the cell surface after agonist-induced internalization. This motif seems to be required for GRK2 and GPRK5/GRK5 to promote agonist-induced internalization (By similarity). Thr-346 is a major site for PKC-induced internalization of the receptor (By similarity).By similarity
