What Is MOTS-c?
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a naturally occurring peptide encoded by mitochondrial DNA. Unlike most peptides, which are encoded by genes in the cell nucleus, MOTS-c originates directly from the mitochondria—the energy-producing structures found within nearly every cell.
Researchers investigate MOTS-c because it appears to act as a signaling molecule between mitochondria and the nucleus, helping cells respond to metabolic stress and changes in energy demand.
Interest in MOTS-c has grown due to its potential role in metabolism, mitochondrial communication, exercise physiology, healthy aging, and cellular resilience.
