Prostaglandin D₂ receptor 1 (DP₁) is a G protein-coupled receptor, encoded by the PTGDR1 gene, for prostaglandin D₂ (PGD₂).^[1]

Mechanism

DP₁ is a G protein-coupled receptor (GPCR). Its activity is mainly mediated by G-S proteins that stimulate adenylate cyclase resulting in an elevation of intracellular cAMP and Ca²⁺.

Function

Knockout studies in mice suggest that the ligand of this receptor, prostaglandin D₂, functions as a mast cell-derived mediator to trigger asthmatic responses.^[1] It also causes vasodilation

Ligands

Agonists

• Prostaglandin D₂ - non-selective
• Treprostinil - non-selective

Antagonists ^[2]

• Asapiprant (S-555739) - selective
• Laropiprant - selective
• Vidupiprant - dual DP₁ and DP₂ antagonist
