What is MOTS-C?

MOTS-C is a naturally occurring peptide encoded by mitochondrial DNA rather than nuclear DNA, making it unique among many signalling peptides.

It belongs to a small family of molecules known as mitochondrial-derived peptides (MDPs), which are produced within the mitochondria—the structures responsible for generating much of the cell's energy.

Since its discovery, MOTS-C has become an increasingly important area of research because scientists continue to investigate how mitochondrial signalling influences whole-body physiology.

How Does MOTS-C Work?

The precise biological mechanisms of MOTS-C remain under active investigation.

Current research suggests it may influence several cellular pathways involved in metabolic regulation and energy homeostasis.

Researchers continue to investigate its potential involvement in:

Cellular metabolism
Energy regulation
Glucose metabolism
Exercise physiology
Cellular stress responses
Mitochondrial signalling

Further research is required to better understand these biological mechanisms.

What Are Mitochondrial-Derived Peptides?

Mitochondrial-derived peptides are naturally occurring signalling molecules encoded by mitochondrial DNA.

Unlike most proteins and peptides, which are encoded within the cell nucleus, these peptides originate directly from the mitochondria.

Researchers continue to investigate how mitochondrial-derived peptides contribute to:

Cellular communication
Metabolic regulation
Stress responses
Ageing biology
Energy homeostasis

MOTS-C is among the best studied members of this peptide family.
