MOTS-c: Discovery & Research History
MOTS-c (Mitochondrial-Derived Peptide) — how it was originally discovered, and what it has been studied for since.
How MOTS-c Was Discovered
MOTS-c is a genuinely unusual discovery: a functional, 16-amino-acid signaling peptide encoded not in the cell's nuclear DNA, but inside mitochondrial DNA itself — specifically, within a short open reading frame inside the 12S rRNA gene. Changhan David Lee's team at the University of Southern California identified it in 2015 and published the discovery in the journal Cell Metabolism.
The finding mattered for two reasons. First, mitochondrial DNA simply wasn't thought to encode signaling peptides at all before this — MOTS-c effectively opened up an entirely new research category, now generally referred to as mitochondrial-derived peptides (MDPs). Second, the original research question concerned metabolic homeostasis and insulin sensitivity, and MOTS-c appeared to play a direct role in mediating the metabolic effects of exercise at the cellular level in skeletal muscle — connecting mitochondrial signaling to whole-body metabolic regulation in a way that hadn't been described before.
What MOTS-c Has Been Studied For
Research interest in MOTS-c centers on exactly the mechanism its discovery pointed to: how a peptide made inside mitochondria can influence metabolism and stress response well beyond the mitochondrion itself.

MOTS-c discovery & history questions
Does MOTS-c's research history mean it's approved for a particular use?
No. This page describes how MOTS-c was originally discovered and what it has been studied for since — it is historical and educational context, not a claim about current regulatory approval, safety, or legal status anywhere. KYIN Peptides sells MOTS-c strictly for laboratory research use.
What has MOTS-c been studied for in research?
MOTS-c is most commonly studied in mitochondrial signaling research, metabolic regulation studies, exercise physiology research models, and cellular stress-response studies.
