Prostaglandin E Receptor 3 (EP3)

Prostaglandin E receptor 3, also known as EP3, is a prostaglandin receptor, The receptor is a member of the G-protein coupled receptor family. It is one of four receptors identified for prostaglandin E2 (PGE2). This receptor may have many biological functions, which involve digestion, nervous system, kidney reabsorption, and uterine contraction activities. In the stomach, it inhibits gastric acid secretions.Studies of the mouse counterpart suggest that this receptor may also mediate adrenocorticotropic hormone response as well as fever generation in response to exogenous and endogenous stimuli.Multiple alternatively spliced transcript variants encoding eight distinct isoforms have been reported.
