MOTS-c
Mitochondrial-derived peptide
A 16-residue peptide encoded within mitochondrial 12S rRNA, studied as an AMPK-linked regulator of metabolic homeostasis and mitochondrial-to-nuclear signalling.
MOTS-c is one of a small number of known mitochondrial-derived peptides. It has been shown to activate AMPK via the folate–methionine cycle and to translocate to the nucleus under metabolic stress.
Human data is limited to observational measurement of endogenous circulating levels; no human administration trials have been verified. Supplied lyophilised. Not an approved medicine.
