Target Background

Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(s) proteins that stimulate adenylate cyclase. Has a relaxing effect on smooth muscle. May play an important role in regulating renal hemodynamics, intestinal epithelial transport, adrenal aldosterone secretion, and uterine function.
Gene References into Functions
  1. EP4 is a novel regulator of bile acid synthesis, and its activation protects against hypercholesterolemia. PMID: 29890224
  2. Paricalcitol also attenuated the infiltration of inflammatory cells and production of proinflammatory cytokines after IR injury.

  16. Data suggest that PGE2/Ep4 (prostaglandin E receptor 4; Ptger4) signaling via cAMP/Epac (exchange protein directly activated by cAMP 1; Rapgef3) induces expression of Icam1 (intercellular adhesion molecule 1) in cerebrovascular endothelial cells. PMID: 23317035
