MOTS-c
What Is MOTS-c?
MOTS-c is a 16–amino acid peptide encoded within the mitochondrial genome and translated in the cytoplasm. In laboratory research, MOTS-c is studied for its role in cellular metabolism, mitochondrial signaling, and adaptive stress-response pathways. Its discovery expanded the understanding of mitochondria as active signaling organelles, not solely energy producers.

Third-party tested for 99% purity
History and Discovery
MOTS-c was first described in 2015 following the identification of short open reading frames encoded within mitochondrial DNA. Researchers discovered that MOTS-c functions as a regulator of metabolic signaling, with particular relevance to AMP-activated protein kinase (AMPK) activation and cellular stress resistance.
This finding significantly advanced mitochondrial biology by demonstrating that mitochondria encode bioactive peptides capable of influencing whole-cell and systemic metabolic regulation.

Research Findings
MOTS-c has been examined across metabolic, cellular, and systemic research models. Published studies highlight its involvement in mitochondrial signaling, energy regulation, glucose utilization, insulin sensitivity, and cellular stress adaptation in preclinical settings.
Key Areas of Investigation:
- Metabolic: Glucose metabolism, insulin signaling, energy balance
- Cellular: Mitochondrial function, stress response pathways, cellular repair
- Systemic: Cytoprotection, recovery signaling, physiological resilience
Collectively, these findings suggest broad experimental utility for MOTS-c across multiple biological domains. By engaging mitochondrial-encoded signaling pathways and modulating energy and stress responses, MOTS-c provides a versatile platform for research into metabolic regulation, cellular recovery, and systemic resilience in laboratory models.
