Ghrelin is a 28-amino-acid hunger hormone requiring unique post-translational octanoylation for receptor activation — a key example of peptide modification biology.
Ghrelin is a 28-amino-acid hunger hormone requiring unique post-translational octanoylation for receptor activation — a key example of peptide modification biology.
Source & context
Biological / chemical source: Stomach
Primary research or clinical context: Metabolism & appetite research
Post-translational modification
The n-octanoyl group on serine-3 is essential for binding the growth hormone secretagogue receptor (GHS-R). Without it, des-acyl ghrelin has different biology.
