PTGDR2 (prostaglandin D2 receptor 2), CRTH2 (chemoattractant receptor-homologous molecule expressed on TH2 cells) or CD294,  is a 7-transmembrane protein of the G protein-coupled receptor 1 (GPCR1) family.  PTGDR2 is preferentially expressed in CD4+ effector T helper 2 (Th2) cells. PTGDR2 is a prostaglandin D2 (PGD2) receptor that mediates the pro-inflammatory chemotaxis of eosinophils, basophils, and Th2 lymphocytes generated during allergic inflammation. PTGDR2 signaling is coupled to the G(i)-protein. Its activation may result in pertussis toxin-sensitive decreases in cAMP levels and Ca2+ mobilization. PI3K signaling is also implicated in mediating PTGDR2 effects. PGD2 induces PTGDR2 internalization. that can be regulated by diverse kinases such as, PKC, PKA, GRK2, GPRK5/GRK5 and GRK6. PTGDR2 signaling activation is responsible, at least in part, in immune regulation and allergic/inflammation responses.

Product Details

 

Gene Symbol: PTGDR2; CD294; DP2; DL1R; CRTH2; GPR44

 

NCBI Gene ID: 11251

 

Uniprot Entry: Q9Y5Y4

 

Construct Details: Full length human PTGDR2 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without an antibiotic selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 1188 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
