Abstract
MOTS-C (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded by the mitochondrial genome. It is studied in preclinical research as a bioactive mitochondrial-derived peptide (MDP) involved in metabolic regulation and cellular stress response.
Chemical Structure and Properties
MOTS-C is a short peptide consisting of the sequence:
MRWQEMGYIFYPRKLR
It is naturally produced in mitochondria and can be synthesized for laboratory use. Its small size and unique origin make it an interesting subject for studies on mitochondrial-encoded bioactive molecules.
