MOTS-c

Mitochondrial Open Reading Frame of the 12S rRNA Type-c

Evidence & Status

  • Preliminary / Experimental
  • Preliminary

At a Glance

A 16-amino-acid peptide encoded within mitochondrial DNA, discovered in 2015. Studied for its roles in metabolic regulation, insulin sensitivity, and longevity biology. Often discussed as a potential exercise-mimetic compound due to its overlapping effects with physical activity at the cellular level.

Plain English

Researchers study MOTS-c because it is produced within mitochondria — the energy-generating structures inside cells — and appears to travel to the cell's nucleus to help the body respond to metabolic stress. Scientists are interested in its potential connections to insulin sensitivity, healthy aging, and the biological pathways activated by exercise. Circulating levels of MOTS-c have been observed to decline with age, which has led researchers to investigate whether this decline plays a role in age-related metabolic changes. It is one of the more recently discovered compounds in the database, and research is still in relatively early stages.

Overview

MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded within the 12S rRNA gene. It is studied as a metabolic stress signal involving AMPK and related pathways. Animal and mechanistic studies examine glucose handling, insulin sensitivity, obesity, exercise, and longevity biology; these findings do not establish human interventional efficacy.

Research Summary

MOTS-c is a mitochondrial-derived peptide discovered as a metabolic stress signal. The cited work is preclinical and examines metabolic homeostasis, obesity, insulin sensitivity, and related exercise biology in animal models. These findings do not establish human efficacy, a self-administration schedule, or a universal pharmacokinetic profile.

Research Areas
