Mechanism of Action

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA Type-c) is a 16-amino-acid microprotein encoded within the mitochondrial 12S rRNA gene rather than the nuclear genome. Under metabolic stress it translocates from the mitochondria into the cytoplasm and nucleus to coordinate the cellular stress response. In the cytoplasm it inhibits the folate-methionine cycle enzyme MTHFD2, which lowers de novo purine synthesis and allows AICAR to accumulate; rising AICAR activates the AMPK energy-sensing pathway, the same master switch triggered by aerobic exercise and metformin. Once inside the nucleus, MOTS-c docks at antioxidant response elements (AREs) and drives transcription of stress-defence and metabolic genes via NRF2. Circulating MOTS-c falls with age and rises sharply after exercise, which is why it is framed as a retrograde signal that lets the mitochondrion instruct the rest of the cell.

Scientific Research

Why Researchers Choose MOTS-c

MOTS-c is one of the first mitochondrial-derived peptides (MDPs) to be characterised, and it has become a reference tool wherever the link between mitochondrial signalling and whole-body metabolism is investigated. As an AMPK-activating exercise mimetic encoded inside mitochondrial DNA, it appears across several research lines:

  • Mitochondrial retrograde signalling and AMPK pathway activation studies
  • Insulin sensitivity, glucose uptake and metabolic homeostasis research
  • Age-associated physical decline and skeletal-muscle function investigations
  • Exercise-mimetic pharmacology, benchmarked against AICAR and other AMPK activators
  • Folate-methionine cycle and one-carbon metabolism studies
  • Mitochondria-derived peptide biology and cell-to-nucleus communication

Reconstitution and Storage

Reconstitution: use bacteriostatic water (1 to 2ml per 40mg vial); swirl gently until fully dissolved, do not shake. After reconstitution: keep refrigerated at 2-8°C, protect from direct light, and use within 28 days.
