What is MOTS-c?

MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded by mitochondrial DNA. It is studied in preclinical models for its role in metabolic homeostasis, insulin sensitivity, and AMPK-pathway signaling.

MOTS-c ("Mitochondrial Open Reading frame of the 12S rRNA-c") is a 16-amino-acid peptide encoded within mitochondrial DNA itself — a relatively recent discovery in mitochondrial biology.

Research focus:

  • AMPK-pathway activation — MOTS-c is studied as an activator of the AMPK energy-sensing pathway.
  • Insulin sensitivity and glucose handling in preclinical metabolic models.
  • Mitochondrial-nuclear signaling — MOTS-c is one of a growing class of "mitokines" that signal between the mitochondrion and the nucleus.
  • Exercise mimetic research — its pathway overlap with exercise-responsive signaling has drawn investigator attention.

MOTS-c sits at the intersection of the Mitochondrial, Metabolic, and Longevity research pathways and is supplied for laboratory investigation only.
