| HMRbase accession number | 10367 |
| Swiss-prot Accession number | Q9UBU3 (Sequence in FASTA format) |
| 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) |
| Taxonomical Classification | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini;Catarrhini; Hominidae; Homo. |
| Subcellular location | Secreted protein |
| Developmental Stage | N/A |
| Similarity | Belongs to the motilin family. |
| Tissue Specificity | Highest level in stomach. All forms are found in serum as well. Other tissues compensate for the loss of ghrelin synthesis in the stomach following gastrectomy |
| 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 |
