MOTS-c: Mitochondrial-Derived Peptide Research Overview

Quick Answer
MOTS-c is a 16-residue peptide (MRWQEMGYIFYPRKLR) encoded by a short open reading frame inside the mitochondrial 12S rRNA gene, which makes it one of the few known mitochondrial-derived peptides. Formula C101H152N28O22S2, molecular weight 2174.6 g/mol, CAS 1627580-64-6. It is studied in AMPK signaling, folate-methionine cycle research and mitochondrial-to-nuclear communication in cell lines.

A Peptide Encoded in Mitochondrial DNA
Most proteins in a cell are encoded by nuclear DNA. Mitochondria keep a small genome of their own, and short open reading frames within it can encode small peptides. MOTS-c was identified from one of these frames within the 12S rRNA gene. Because its sequence is short and fully defined, identity on a certificate is confirmed directly against the 16-residue sequence.
Research Areas
- AMPK activation in cell lines
- Folate-methionine cycle research
- Mitochondrial-to-nuclear signaling
MOTS-c is often compared with SS-31, a synthetic peptide that targets the inner mitochondrial membrane; see SS-31 vs MOTS-c. It is also supplied with NAD+ and SS-31 in the NAD+ + MOTS-c + SS-31 research bundle.
Storage of the Sealed Vial
The compound ships as a lyophilized (freeze-dried) solid in a sealed vial labelled with its lot number. Store sealed vials as stated on the label, protected from light and moisture; see our storage and handling guide for temperature ranges.
Analytical Verification and Documentation
Each lot is tested by Testides, an independent laboratory, for HPLC purity and content, and the certificate is published with its report number so it can be checked against the lab’s record: MOTS-c 10 mg certificate and MOTS-c 40 mg certificate. New to certificates? Read how to read a COA.
