MOTS-c (Mitochondrial ORF of the Twelve S rRNA-c) is a 16-amino acid mitochondrial-derived peptide (MDP) encoded by the 12S rRNA region of the mitochondrial genome . Discovered in recent years, it represents a novel class of bioactive peptides that act as mitochondrial hormones, regulating cellular metabolism and stress responses .
Key Specifications:
Molecular Formula: C₆₉H₁₁₁N₂₁O₁₈S (approx.)
Molecular Weight: ~1587 Da
Sequence: 16 amino acids
Purity: ≥95-98% (research grade)
Appearance: Lyophilized powder

Mechanism of Action: MOTS-c acts as a mitochondrial signaling molecule with pleiotropic effects :
AMPK pathway activation: Enhances AMPK activity, promoting glucose uptake, fatty acid oxidation, and mitochondrial biogenesis
Nuclear translocation: During metabolic stress, MOTS-c translocates to the nucleus and regulates nuclear gene expression
Insulin sensitivity: Improves insulin sensitivity in skeletal muscle and systemic glucose metabolism
Anti-inflammatory effects: Reduces pro-inflammatory cytokines and oxidative stress
Cellular stress adaptation: Supports cellular adaptation during metabolic stress (fasting, exercise)
