How to read this MOTS-c research page

This page summarizes MOTS-c literature by experimental theme, including mitochondrial encoding, AMPK-pathway research, nuclear translocation, and model-system gene regulation. It is a published-literature map and documentation companion, not a protocol or human-use resource.

  • Compound identity: MOTS-c is discussed here as a mitochondrial-derived peptide sequence in laboratory research literature.
  • Research framing: summaries focus on pathway assays and experimental models; they do not establish product claims or intended uses.
  • Documentation links: compare the MOTS-c catalog listing, COA hub, y research framework.

MOTS-c Discovery and Mitochondrial Encoding

MOTS-c was identified in 2015 as a peptide encoded within a short open reading frame in the 12S rRNA region of mitochondrial DNA. Unlike nuclear-encoded peptides, MOTS-c is translated using the mitochondrial genetic code and exported to the cytoplasm and circulation. Reported plasma MOTS-c levels vary by age and metabolic state across published cohorts. The discovery of MOTS-c expanded the concept of mitochondria as signaling organelles that communicate with the nucleus and other tissues.

AMPK Activation and Metabolic Signaling

MOTS-c activates AMP-activated protein kinase (AMPK), the master regulator of cellular energy homeostasis. The mechanism involves MOTS-c inhibition of the folate-methionine cycle, specifically by binding to and inhibiting methionine adenosyltransferase 2A (MAT2A), leading to decreased S-adenosylmethionine (SAM) levels and de-repression of AMPK. AMPK activation then stimulates glucose uptake, fatty acid oxidation, and mitochondrial biogenesis while inhibiting lipogenesis and gluconeogenesis.

MOTS-c Nuclear Translocation and Gene Regulation

Under metabolic stress conditions, MOTS-c translocates to the nucleus where it regulates gene expression involved in cellular stress responses. Nuclear MOTS-c interacts with ARE (antioxidant response element)-containing gene promoters and modulates transcription of genes including NRF2 targets. This represents a unique form of retrograde signaling where a mitochondrial-encoded peptide directly regulates nuclear gene transcription. Exercise increases MOTS-c nuclear translocation in skeletal muscle cells.
