The anterior pituitary, pancreatic islets, thyroid gland, heart, and different parts of the brain have high expression levels of the seven transmembrane G protein-coupled receptor known as GHSR (growth hormone secretagogue receptor). GHS-R1a and GHS-R1b are the two types of GHS-R that are recognized as existing.
Gastric polypeptide ghrelin activates the GHS-R1a in the hypothalamus-pituitary axis, where it exhibits strong GH-releasing activity. When ghrelin or artificial peptidyl and non-peptidyl ghrelin-mimetic agents, known as GHS, bind to the GHS-R1a, a G-protein-coupled receptor, it preferentially couples to Gq, ultimately increasing the intracellular calcium content. Ghrelin and GHS also have significant effects on food intake, gut motility, sleep, memory, and behavior in addition to their powerful GH-releasing action. They also affect cardiovascular performance, cell proliferation, immune responses, and reproduction.
