# MOTS-c > Mitochondrial-derived peptide studied for metabolic health. Source: https://peptides.cafe/peptide/mots-c Category: Mitochondrial ยท Metabolic Tag: Longevity ## Mechanism A 16-amino-acid peptide encoded within the mitochondrial 12S rRNA gene. Research suggests it activates AMPK, enhances insulin sensitivity, and regulates nuclear gene expression in response to metabolic stress โ€” positioning it as a candidate mitochondrial-nuclear signaling peptide. ## Research areas - Insulin sensitivity - Exercise capacity and mitochondrial biogenesis - Age-related metabolic decline - Obesity models ## Common research protocols - Subcutaneous research: Investigational dosing in animal metabolic studies. ## Study summaries - "The mitochondrial-derived peptide MOTS-c promotes metabolic homeostasis" โ€” Cell Metabolism (2015): Foundational paper establishing AMPK-dependent metabolic effects. - "MOTS-c levels decline with age" โ€” Aging (2018): Circulating MOTS-c associated with age-related metabolic phenotypes. ## Considerations - Early-stage research; no approved human therapeutic use. - Long-term effects unknown. ## Disclaimer Educational content only.
