- us
MOTS-C is a 16-amino-acid mitochondrial-derived peptide encoded within the mitochondrial 12S rRNA region. Published research examines metabolic homeostasis, AMPK-associated signaling, mitonuclear communication, exercise responses and age-related physiology. Evidence concerning externally supplied MOTS-C remains predominantly preclinical.

Mitochondrial origin. Sixteen amino acids.
MOTS-C is encoded by a short open reading frame within the mitochondrial 12S rRNA region. The human sequence MRWQEMGYIFYPRKLR has been studied as a signal connecting mitochondrial metabolic state with cellular and nuclear responses.
MRWQEMGYIFYPRKLR
A linear peptide containing 16 amino-acid residues.
Mitochondrial 12S rRNA region
MOTS-C belongs to the mitochondrial-derived peptide family.
Metabolic-stress signaling
Published studies examine AMPK, folate and purine metabolism, nuclear stress responses and exercise biology.
The MOTS-C molecule
An interactive illustrative atomic representation generated from the public compound record, alongside verified molecular data. The figure is schematic and is not a measured solution conformation.
Published research observations.
Selected cell, animal and observational human findings are shown for research context. They do not establish the efficacy, safety or suitability of externally supplied MOTS-C in humans.
Mitochondrial-derived peptide
The human reference sequence is MRWQEMGYIFYPRKLR.
Metabolic homeostasis studied
The original Cell Metabolism report examined glucose regulation and insulin sensitivity in cellular and mouse models.
Exercise response examined
Endogenous MOTS-C was measured in human exercise samples, while intervention experiments were performed in mice and cells.
Mitochondrial signal. Multiple adaptive pathways.
MOTS-C research links mitochondrial metabolism with cytosolic energy sensing and stress-dependent nuclear gene regulation. The described mechanisms depend on model and experimental conditions.
Energy-sensing pathways
Cell and animal studies connect MOTS-C with folate and purine metabolism, AICAR-related signaling and AMPK activation.
Mitonuclear communication
Under metabolic stress, MOTS-C has been reported to translocate to the nucleus and influence stress-responsive gene expression.
Exercise and metabolic adaptation
Published work examines endogenous exercise responses, skeletal-muscle metabolism and physical-capacity outcomes in experimental models.
