EP1 inhibition

Patent Pending Prostaglandin E receptor 1 (subtype EP1) is a 42kDa prostaglandin receptor. PTGER1 is its human gene.[1] 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, Gq 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.
