MOTS-c: A Laboratory Research Reference

MOTS-c is a synthetic peptide encoded within the mitochondrial genome, and is of research interest because it originates from mitochondria rather than the nuclear genome. It is studied in laboratory research for its role in cellular metabolism, particularly metabolic signalling intended to restore balance during metabolic stress.

Chemical Identity and Origin

MOTS-c is a 16-amino-acid peptide derived from within the mitochondrial 12S ribosomal RNA. Its mitochondrial origin distinguishes it from most studied peptides, which are nuclear-encoded, and this is a point of active research interest — it represents one of a class of mitochondrial-derived peptides implicated in metabolic signalling.

As a synthetic peptide, MOTS-c is assembled in the laboratory, then purified and characterised before it is supplied for research. For background on production and verification, see the synthetic peptides research guide.

Mechanism as Studied

The research literature describes MOTS-c as involved in the regulation of cellular metabolism, including pathways related to nutrient sensing and the cellular response to metabolic stress. Its proposed mechanisms centre on metabolic signalling rather than a single classical receptor, which contributes to its status as an actively investigated mitochondrial-derived peptide. Findings remain preclinical.
