MOTS-c

Also known as: mitochondrial open reading frame of the 12S rRNA type-c

PeptidePreclinical only16 residuesMitochondrial & cellular bioenergetics

A mitochondrial-derived peptide encoded within the mitochondrial 12S rRNA gene rather than the nuclear genome — a class of molecule only recognised comparatively recently.

Development status: Preclinical — laboratory and animal studies only

Identifiers are published only with a source and a check date. Fields marked “not verified” have not yet been confirmed against a primary source — we show the gap rather than an unchecked figure. Always confirm against the certificate of analysis for the specific lot you hold.

Biological targets

  • AMPK pathway (reported)
  • Folate–methionine cycle metabolites (reported)

Mechanism of action

Reported to influence metabolic regulation via AMPK signalling and the folate cycle. As with other mitochondrial-derived peptides, whether exogenously administered peptide reproduces endogenous signalling is unresolved.

Research evidence and its limits

Cell and rodent studies. No completed human efficacy trials known to this entry.

Safety considerations

No regulatory authority has assessed this compound as safe or effective for any human indication. The published record is predominantly laboratory and animal work, which does not establish human safety. Supplied and discussed here strictly as a laboratory research material. Not a medicine, not for human or veterinary administration, and nothing on this page should be read as a dosing, treatment or safety recommendation.

Analytical identification and quality testing

Identity by high-resolution mass spectrometry against the expected mass, purity by RP-HPLC with UV detection. For a sequence-defined peptide, enzymatic digestion followed by peptide mapping gives far stronger identity evidence than mass alone, because isomers and closely related sequences can share a mass.

Regulatory status

Not an approved medicine.

Frequently asked questions

What makes a peptide "mitochondrial-derived"?

It is encoded by mitochondrial DNA rather than nuclear DNA. Mitochondria carry their own small genome, and short open reading frames within it were found to encode bioactive peptides — MOTS-c and humanin are the best known.
