Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Cell membrane; Multi-pass membrane protein.

Disease Associations

Tissue Specificity

Abundant expression in ileum, thymus and mastocytoma P-815 cells. Also observed in lung, spleen, heart and uterus.
