🧠 Key Notes
What makes it distinct
- 01Encoded within mitochondrial DNA
- 02Frequent subject of metabolic flexibility studies
- 03Short systemic presence, sustained downstream signalling
🧬 Mechanism of Action
How it works
MOTS-c is a 16-amino-acid peptide encoded within the 12S rRNA region of mitochondrial DNA — making it a rare mitochondrial-derived signalling molecule. It activates AMP-activated protein kinase (AMPK), the master cellular energy sensor, producing effects similar to caloric restriction and exercise: increased glucose uptake (via GLUT4 translocation), enhanced fatty-acid oxidation, and improved mitochondrial biogenesis. It also translocates to the nucleus under metabolic stress to regulate adaptive gene expression, positioning it as a true mitochondrial-to-nuclear retrograde signal.
