MOTS-C is a mitochondrial-derived research peptide composed of 16 amino acids and encoded within the mitochondrial 12S ribosomal RNA (MT-RNR1) gene. Its mitochondrial origin distinguishes MOTS-C from many conventional research peptides and has made it an area of laboratory investigation involving cellular metabolism, mitochondrial signaling, energy regulation, and responses to metabolic stress.

MOTS-C research has explored its relationship with metabolic signaling pathways involved in glucose utilization and cellular energy balance. Researchers have investigated its interactions with AMP-activated protein kinase (AMPK), an important cellular energy sensor involved in regulating metabolic activity in response to changes in energy availability.

Another significant area of MOTS-C research involves mitochondrial-to-nuclear communication. Laboratory studies have examined how MOTS-C may participate in signaling between mitochondria and the nucleus, including cellular responses associated with metabolic stress, mitochondrial function, and age-related biological changes.

MOTS-C has a molecular weight of approximately 2,174.6 g/mol and can be synthetically produced for controlled research applications. It is typically supplied as a lyophilized powder for laboratory investigation involving mitochondrial biology, metabolic signaling, cellular energy regulation, and related biochemical pathways.
