Description

Appetite-regulating hormone precursor (Growth hormone secretagogue)(Growth hormone-releasing peptide) (Motilin-related peptide)[Contains: Ghrelin; Obestatin].

Source Organism

Canis familiaris (Dog).

Taxomomy

Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Mammalia; Eutheria; Laurasiatheria; Carnivora; Caniformia; Canidae;Canis.

Subcellular Localization

Secreted protein.

Developmental Stage

Similarity

Belongs to the motilin family.

Post translational Modification

O-n-octanoylation is essential for ghrelin activity (By similarity). Amidation of Leu-98 is essential for obestatin activity (By similarity).

Function

Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR). Induces the release of growth hormone from the pituitary. Has an appetite-stimulating effect, induces adiposity and stimulates gastric acid secretion. Involved in growth regulation
