Description

Overview

MOTS-c is a small bioactive peptide encoded within the mitochondrial genome, making it a novel subject in the growing field of mitochondrial-derived peptides (MDPs). Researchers are particularly drawn to MOTS-c for its apparent involvement in cellular energy regulation and adaptive stress responses, highlighting the emerging role of mitochondria as active signaling hubs beyond their traditional energy production function.

As a mitochondrial-encoded peptide, MOTS-c provides a unique window into mitochondrial-to-nuclear communication processes, also known as mitohormesis. Researchers use MOTS-c to study how mitochondria-derived signals influence cellular metabolism, stress resilience, and adaptive gene expression across diverse experimental models. Its compact sequence and mitochondrial origin make it a valuable research tool for exploring the evolving interface between metabolism, peptide signaling, and cellular homeostasis.
