MOTS-c: The Mitochondrially-Derived Metabolic Peptide
MOTS-c is encoded inside mitochondrial DNA - not the nucleus. What a mitochondrially-derived peptide is, and the metabolic and AMPK research that made MOTS-c a longevity-science focus.
MOTS-c is unusual among research peptides: it is encoded not in the nucleus but inside mitochondrial DNA. This article explains what a mitochondrially-derived peptide is and the metabolic research that surrounds MOTS-c.
A peptide encoded in mitochondrial DNA
Most peptides are encoded by nuclear genes. MOTS-c (Mitochondrial Open reading frame of the Twelve S rRNA-c) is encoded within a short open reading frame inside the mitochondrial 12S rRNA. It was the first widely-studied member of the mitochondrial-derived-peptide (MDP) family, a discovery that reframed how researchers think about mitochondria as signaling organelles.
What the research has examined
- AMPK activation and cellular metabolic-stress signaling
- Effects on insulin sensitivity in preclinical models
- Regulation of metabolic homeostasis under nutrient stress
Why it matters to longevity research
Because mitochondrial function and metabolic flexibility are central themes in aging research, a mitochondrially-encoded peptide that appears to participate in metabolic regulation is of natural interest. MOTS-c sits alongside compounds like NAD+ in the cellular-energy research conversation.
Quality and verification
Caesar Biomedical MOTS-c ships as a reference-grade research compound with per-lot identity confirmation by ESI-MS, independently verified in Dubai or the UK.

Frequently asked questions
- What is a mitochondrially-derived peptide?
- It is a peptide encoded within mitochondrial DNA rather than nuclear DNA. MOTS-c was the first such peptide to be studied widely.
