Purification and Characterization of Rat des-Gln14-Ghrelin, a Second Endogenous Ligand for the Growth Hormone Secretagogue Receptor
Open accessAbstract
Ghrelin, a peptide purified from the stomach, is an endogenous ligand for the growth hormone secretagogue receptor (GHS-R) and potently stimulates growth hormone release from the pituitary. Ghrelin is modified with an n-octanoyl group at Ser(3). This modification is essential for the activity of ghrelin. Previously, it was not known whether other ligands for GHS-R existed. Here, we report the purification of the second endogenous ligand for GHS-R from rat stomach. This ligand, named des-Gln(14)-ghrelin, is a 27-amino acid peptide, whose sequence is identical to ghrelin except for one glutamine. Southern blotting analysis under low hybridization conditions indicates that no homologue for ghrelin exists in rat genomic DNA. Furthermore, genomic sequencing and cDNA analysis indicate that des-Gln(14)-ghrelin is not encoded by a gene distinct from ghrelin but is encoded by an mRNA created by alternative splicing of the ghrelin gene. This is the first example of a novel mechanism that produces peptide multiplicity. Des-Gln(14)-ghrelin has an n-octanoyl modification at Ser(3) like ghrelin, which is also essential for its activity. Des-Gln(14)-ghrelin-stimulated growth hormone releases when injected into rats. Thus, growth hormone release is regulated by two gastric peptides, ghrelin and des-Gln(14)-ghrelin.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
