Description
The gonadotropin-releasing hormone receptor (GNRHR), also known as the luteinizing hormone releasing hormone receptor (LHRHR), is a member of the seven-transmembrane, G-protein coupled receptor (GPCR) family. It is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate. Upon activation, the LHRHr stimulates tyrosine phosphatase and elicits the release of LH from the pituitary. Evidence exists showing the presence of LHRH and its receptor in extrapituitary tissues as well as a role in progression of some cancers.
