Prostanoid receptors in GtoPdb v.2021.2

Abstract

Prostanoid receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Prostanoid Receptors [694]) are activated by the endogenous ligands prostaglandins PGD₂, PGE₁, PGE₂ , PGF_2α, PGH₂, prostacyclin [PGI₂] and thromboxane A₂. Differences and similarities between human and rodent prostanoid receptor orthologues, and their specific roles in pathophysiologic conditions are reviewed in [448]. Measurement of the potency of PGI₂ and thromboxane A₂ is hampered by their instability in physiological salt solution; they are often replaced by cicaprost and U46619, respectively, in receptor characterization studies.
