Summaries for PTGER1 Gene

Entrez Gene Summary for PTGER1 Gene

  • The protein encoded by this gene is a member of the G protein-coupled receptor family. This protein is one of four receptors identified for prostaglandin E2 (PGE2). Through a phosphatidylinositol-calcium second messenger system, G-Q proteins mediate this receptor's activity. Knockout studies in mice suggested a role of this receptor in mediating algesia and in regulation of blood pressure. Studies in mice also suggested that this gene may mediate adrenocorticotropic hormone response to bacterial endotoxin. [provided by RefSeq, Jul 2008]

GeneCards Summary for PTGER1 Gene

PTGER1 (Prostaglandin E Receptor 1) is a Protein Coding gene. Diseases associated with PTGER1 include Tinea Barbae and Antenatal Bartter Syndrome. Among its related pathways are Peptide ligand-binding receptors and Eicosanoid ligand-binding receptors. GO annotations related to this gene include G-protein coupled receptor activity and prostaglandin E receptor activity. An important paralog of this gene is TBXA2R.

UniProtKB/Swiss-Prot for PTGER1 Gene

  • Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(q) proteins which activate a phosphatidylinositol-calcium second messenger system. May play a role as an important modulator of renal function. Implicated the smooth muscle contractile response to PGE2 in various tissues.

Tocris Summary for PTGER1 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.
