Ghrelins and Obestatins Peptides

Catalog Go™ peptides

Ghrelin is a 28-amino-acid peptide hormone produced by the stomach in mammals. The major active form of Ghrelin is a peptide with an n-octanoyl modification at Ser3 (n-octanoyl Ghrelin). Endogenous Ghrelin participates in the regulation of food intake and body weight. The secretion of ghrelin is augmented under conditions of both gastric emptying and filling, and the release is stimulated by intestinal hormones. Ghrelin is also involved in the release of growth hormone from the anterior pituitary through activation of the growth hormone secretagogue receptor (GHS-R). It is also a potent vasodilator that can be detected in endothelial cells of arteries and veins in human. 

Derived from the ghrelin gene, obestatin peptide suppresses food intake, inhibits jejunal contraction, and decreases body-weight gain. Obestatin was thought to bind to the orphan G protein–coupled receptor GPR39; however new data confirm that I125-obestatin does not bind GPR39.

Reference Name Description
AS-62931 [Ala1, D-Trp2,4, Leu6]-Ghrelin Receptor Agonist This peptide is a high potency agonist of the ghrelin receptor.
AS-62930 [D-Trp1,3, Leu5]-Ghrelin Core-Ligand This peptide is an active core-ligand which affects ghrelin receptor with a characteristic low biphasic dose-response curve. At low concentrations, it acts as a partial agonist; at high concentrations as a partial inverse agonist. The aromatic wFw tripeptide is suggested to represent the essential binding unit in the inverse agonists for ghrelin receptors.

AS-61905 C-terminal Proghrelin Isoform Peptide, mouse This is a unique C-terminal peptide encoded by the exon 4 - deleted proghrelin variant. This mouse proghrelin isoform with the complete deletion of exon 4 is potentially generated by alternative splicing of the mouse ghrelin gene. This C-terminal peptide proghrelin isoform is widely expressed in the multiple mouse tissues.
