Gene Name PTGDR
Uniprot ID PD2R_HUMAN
KEGG Pathway hsa:5729
Protein Family G-protein coupled receptor 1 family
Protein Function
Receptor for prostaglandin D2 (PGD2). The activity of this receptor is mainly mediated by G(s) proteins that stimulate adenylate cyclase, resulting in an elevation of intracellular cAMP. A mobilization of calcium is also observed, but without formation of inositol 1,4,5-trisphosphate (By similarity). Involved in PLA2G3-dependent maturation of mast cells. PLA2G3 is secreted by immature mast cells and acts on nearby fibroblasts upstream to PTDGS to synthesize PGD2, which in turn promotes mast cell maturation and degranulation via PTGDR (By similarity).

Recommended Action
      Management Caution and close monitoring for altered efficacy and safety are recommended if patients receive apomorphine with an antihypertensive agent or vasodilator. Patients should be made aware of the possible side effects (e.g., dizziness, lightheadedness, orthostasis) and be cautioned about driving, operating machinery, or performing other hazardous tasks. They should also be advised to avoid rising abruptly from a sitting or recumbent position and to contact their physician if they experience symptoms of hypotension such as dizziness, lightheadedness, or fainting.
