MOTS-c
Also known as: Mitochondrial Open Reading Frame of the 12S rRNA-c
Mitochondrial-Derived Peptide | Metabolic Regulator
Overview
MOTS-c is a mitochondrial-derived peptide that operates as a mitohormone through the Folate-AICAR-AMPK pathway. Under metabolic stress, it translocates to the nucleus to bind stress-response transcription factors (NRF2, ATF1/ATF7), regulating genes involved in metabolism and cellular adaptation.
Key benefits
- Enhanced insulin sensitivity (~30% improvement)
- Improved glucose metabolism and tolerance
- AMPK pathway activation
- Mitochondrial function optimization
- Exercise performance enhancement (12-15% improvement)
- Potential lifespan extension (6.4% median increase in mice)
Mechanism of action
Inhibits the folate cycle leading to AMPK activation. Under metabolic stress, translocates to nucleus to bind stress-response transcription factors, regulating genes involved in metabolism, insulin sensitivity, and cellular adaptation.
