Summaries for PTGDR2 Gene

Entrez Gene Summary for PTGDR2 Gene

  • 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]

GeneCards Summary for PTGDR2 Gene

PTGDR2 (Prostaglandin D2 Receptor 2) is a Protein Coding gene. Diseases associated with PTGDR2 include folliculitis and eosinophilic pustular folliculitis. Among its related pathways are Signaling by GPCR and Innate Lymphoid Cell Differentiation Pathways. GO annotations related to this gene include G-protein coupled receptor activity and prostaglandin F receptor activity. An important paralog of this gene is FPR2.

UniProtKB/Swiss-Prot for PTGDR2 Gene

  • 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.

UniProtKB/Swiss-Prot:

PD2R2_HUMAN :
  • 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.
  • Belongs to the G-protein coupled receptor 1 family.
