Growth hormone secretagogues (GHS) are a group of synthetic peptide and nonpeptide molecules that potently stimulate the release of GH from the anterior pituitary gland through the activation of a novel G-protein-coupled receptor (GPC-R), the GHS-R. In our search for GHS-R family members, we recently described the cloning of two related GPC-Rs, GPR38 and 39. In the present report, we detail the isolation of a new GPC-R (FM-3) from human and mouse with moderate sequence identity to both the GHS-R and neurotensin-R. FM-3 is expressed in a diverse set of tissues.
