| Post Translational Modifications | O-octanoylated by GOAT/MBOAT4. O-octanoylation is essential for ghrelin activity. The replacement of Ser-26 by aromatic tryptophan preserves ghrelin activity. Amidation of Leu-98 is essential for obestatin activity. |
| Function | Ghrelin: 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. Obestatin-23: 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. |
