Prostaglandin receptor

There are currently nine 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:
 * DP2 - PTGDR
 * EP1-4 - PTGER1, PTGER2, PTGER3, PTGER4
 * FP - PTGFR
 * IP - PTGIR

The names of these receptors correspond to the prostaglandin that they bind (e.g., DP1-2 receptors bind to PGD2).
