Description
Product Characteristics:
Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor and is involved in regulating growth hormone release. Ghrelin is derived from a preprohormone called preproghrelin, which also generates a second peptide called obestatin. Obestatin is an endogenous ligand for the orphan G protein-coupled receptor GPR39 and is involved in satiety and decreased food intake. Also known as Appetite regulating hormone, GHRL, Growth hormone releasing peptide, Growth hormone secretagogue, M46 protein, Motilin related peptide, MTLRP, Obestatin, Obestatin preprohormone, PRO1066, UNQ524. Sequence notes: Gly-Ser-Ser-Phe-Leu-Ser-Pro- Glu-His-Gln-Lys-Ala-Gln-Gln-Arg-Lys-Glu- Ser-Lys-Lys-Pro-Pro-Ala-Lys-Leu-Gln-Pro- Arg (mo, rat)
Subcellular location: Secreted
Synonyms: Appetite-regulating hormone, growth hormone secretagogue, growth hormone-releasing peptide, motilin-related peptide, protein M46, grehlin
Target Information: This gene encodes ghrelin-obestatin preproprotein, which generates ghrelin and obestatin. Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor and is involved in regulating growth hormone release. Obestatin was initially reported to be an endogenous ligand for the orphan G protein-coupled receptor GPR39 and was involved in satiety and decreased food intake\, however, these findings are controversial. Recent reports show that obestatin is involved in inhibiting thirst and anxiety, improving memory, regulating sleep, affecting cell proliferation, and increasing the secretion of pancreatic juice enzymes. Alternative promoters and alternative splicing result in multiple transcript variants, some of which encode different protein isoforms and some of which do not encode a protein but may regulate the ghrelin-obestatin preproprotein expression. In addition, antisense transcripts for this gene have been identified and may also function in regulation of the ghrelin-obestatin preproprotein expression. [provided by RefSeq, Oct 2008]
