MOTS-c // The Mitochondrial Dossier: A Peptide Written in the Mitochondria
Why a peptide encoded outside the nucleus reshaped metabolic-signaling research.
EuroVials Research Desk // Editorial · Metabolic Research
MOTS-c is one of a small class of peptides encoded within mitochondrial DNA rather than the nucleus. That origin alone put it at the centre of a new line of metabolic-signaling research.
The Peptide From the Wrong Genome
Most peptides are nuclear-encoded. MOTS-c isn't — it's transcribed from mitochondrial DNA, one of a handful of "mitochondrial-derived peptides." Discovered relatively recently (2015), it opened a research question the field hadn't had a molecule for: how mitochondria signal out.
“A signaling molecule from the organelle we thought only received instructions.”
What Makes MOTS-c Notable?
MOTS-c is a 16-amino-acid peptide encoded in the mitochondrial 12S rRNA region — structurally and genetically distinct from nuclear-encoded peptides. That origin is central to its research identity.
