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. Supplied by NexPept as a lyophilized powder for in vitro laboratory research use. This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.

In Vitro Research Context
Mitochondria-derived signalling & metabolic pathway models — laboratory use only
Mitochondria-derived signalling & metabolic pathway models — laboratory use only
MOTS-C is exceptional among research peptides in that its coding sequence resides within the 12S rRNA gene of mitochondrial DNA — one of fewer than a dozen open reading frames (ORFs) in the entire mitochondrial genome known to encode functional peptides. Under conditions of metabolic stress in cellular models, MOTS-C has been demonstrated to translocate from the mitochondrial matrix to the nucleus, where it is proposed to interact with ARE (antioxidant response element) sequences and regulate nuclear gene expression. This mitochondria-to-nucleus communication pathway — retrograde signalling — is an active area of research with MOTS-C serving as a key model compound.
MOTS-C activates AMP-activated protein kinase (AMPK) in cellular models, engaging downstream metabolic signalling cascades including glucose uptake, fatty acid oxidation pathway regulation, and mitochondrial biogenesis signalling.
MOTS-C has been studied for its interaction with the folate cycle — specifically methionine cycle intermediates — providing a mechanistic link between mitochondrial metabolic state and one-carbon metabolism in vitro.
Inhibition of AICAR transformylase (ATIC) in the de novo purine synthesis pathway has been investigated as part of MOTS-C’s mechanism of metabolic pathway modulation in preclinical cellular research settings.
MOTS-C is studied in the context of insulin signalling and glucose metabolism pathway models, including PI3K/AKT cascade interactions and cellular glucose uptake assays in skeletal muscle cell models.
MOTS-C represents a structurally and mechanistically unique class of research peptide — one of only a small number of known mitochondria-derived peptides (MDPs) with a demonstrated role in inter-organelle signalling. Its dual role as both a mitochondrial product and a stress-responsive nuclear transcriptional modulator makes it a valuable tool compound for research at the intersection of metabolic biology, mitochondrial signalling, and gene regulation.
Research context: MOTS-C is an investigational mitochondria-derived peptide studied in scientific research involving AMPK pathway activation, mitochondrial retrograde signalling, and metabolic regulation models. It has not been authorized by Health Canada for human or veterinary use.
