Background: Ghrelin/Obestatin
GHRL (Ghrelin/Obestatin Prepropeptide) is a 117 aa precursor peptide that is processed into three chains, Ghrelin-27 (aa 24-50), Ghrelin-28 (aa24-51) and Obestatin (aa76-98). The prepropeptide is cleaved into proGhrelin, and then further processed into mature Ghrelin by prohormone convertases. Mature Ghrelin is modified with an N-octanoyl group on serine 3 which is required for receptor binding. Ghrelin and Obestatin are predominantly synthesized in the gastric mucosa. Ghrelin plays a role in growth factor release and appetite suppression as well as many other functions in a variety of organs. Obestatin is a putative hormone that has been suggested to have opposite effects on growth factor release and appetite as Ghrelin.
