Summaries for PTGIR Gene

Entrez Gene Summary for PTGIR Gene

  • The protein encoded by this gene is a member of the G-protein coupled receptor family 1 and has been shown to be a receptor for prostacyclin. Prostacyclin, the major product of cyclooxygenase in macrovascular endothelium, elicits a potent vasodilation and inhibition of platelet aggregation through binding to this receptor. [provided by RefSeq, Jul 2008]

GeneCards Summary for PTGIR Gene

PTGIR (Prostaglandin I2 (Prostacyclin) Receptor (IP)) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and guanyl-nucleotide exchange factor activity. An important paralog of this gene is TBXA2R.

UniProtKB/Swiss-Prot for PTGIR Gene

  • Receptor for prostacyclin (prostaglandin I2 or PGI2). The activity of this receptor is mediated by G(s) proteins which activate adenylate cyclase

Tocris Summary for PTGIR Gene

  • Prostanoid receptors are activated by the endogenous ligands prostaglandin (PG) D2, PGE2, PGF2alpha, PGH2, prostacyclin (PGI2) and thromboxane A2. Cyclooxygenase (COX) converts arachidonic acid to PGH2, from which the other prostaglandins are synthesized. Prostanoid receptors are a family of nine G-protein-coupled receptors that have distinct tissue distributions and actions. IP receptors are coupled to Galphas and are involved in pain mediation, relaxation of vascular smooth muscle, inhibition of platelet aggregation and they contribute to cardiovascular health.

  • Isoprenylation does not influence ligand binding but is required for efficient coupling to the effectors adenylyl cyclase and phospholipase C.
  • Palmitoylation of either Cys-308 or Cys-311 is sufficient to maintain functional coupling to G(s) and signaling.
  • Glycosylation at Asn7
  • Modification sites at PhosphoSitePlus
