MOTS-C

MOTS-C (Mitochondrial Open reading frame of the twelve S rRNA-c, CAS# 1627580-64-6) is a 16-amino-acid mitochondria-derived peptide (MDP) encoded within the 12S rRNA gene of mitochondrial DNA — making it one of a small class of bioactive peptides with a mitochondrial rather than nuclear genomic origin. MOTS-C is studied in preclinical research for its role in mitochondria-to-nucleus retrograde signalling and its involvement in AMPK pathway activation, the folate cycle, de novo purine synthesis, and metabolic regulation models. Under cellular stress conditions, MOTS-C has been shown to translocate from mitochondria to the nucleus in vitro, where it interacts with nuclear gene regulatory elements.
