Prostaglandin receptor, a sub-family of cell surface seven-transmembrane receptors, are the G-protein-coupled receptors. There are currently ten known prostaglandin receptors on various cell types. Prostaglandins bind to a subfamily of cell surface seven-transmembrane receptors, G-protein-coupled receptors. These receptors are named: DP1-2-DP1, DP2 receptors, EP1-4-EP1, EP2, EP3, EP4 receptors, FP-FP, IP1-2-IP1, IP2 receptors, TP-TP receptor. The prostaglandins are a group of hormone-like lipid compounds that are derived enzymatically from fatty acids and have important functions in the animalbody. There are currently ten known prostaglandin receptors on various cell types.
