Description

Appetite-regulating hormone precursor (Growth hormone secretagogue)(Growth hormone-releasing peptide) (Motilin-related peptide) (M46protein) [Contains: Ghrelin-27; Ghrelin-28 (Ghrelin); Obestatin].

Source Organism

Homo sapiens (Human).

Taxomomy

Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini;Catarrhini; Hominidae; Homo.

Subcellular Localization

Secreted protein.

Developmental Stage

Similarity

Belongs to the motilin family.

Post translational Modification

O-n-octanoylation is essential for ghrelin activity. The O-n- decanoylated forms Ghrelin-27-C10 and Ghrelin-28-C10 differ in the length of the carbon backbone of the carboxylic acid bound to Ser- 26. A small fraction of ghrelin, ghrelin-28-C10:1, may be modified with an unsaturated carboxylic acid. 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
