| Description | Appetite-regulating hormone precursor (Growth hormone secretagogue)(Growth hormone-releasing peptide) (Motilin-related peptide)[Contains: Ghrelin; Obestatin]. |
| Source organism | Bos taurus (Bovine) |
| Taxonomical Classification | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Mammalia; Eutheria; Laurasiatheria; Cetartiodactyla; Ruminantia;Pecora; Bovidae; Bovinae; Bos. |
| Subcellular location | Secreted protein (By similarity) |
| Developmental Stage | N/A |
| Similarity | Belongs to the motilin family. |
| Tissue Specificity | N/A |
| Post translational modification | O-n-octanoylation is essential for ghrelin activity (By similarity). Amidation of Leu-97 is essential for obestatin activity (By similarity). |
| Function | Obestatin may be the ligand for GPR39. May have an appetite-reducing effect resulting in decreased food intake. May reduce gastric emptying activity and jejunal motility |
| Protein Length | 116 Amino acids |
| Molecular weight | 12793 |
