MOTS-c

MOTS-c (mitochondrial open reading frame of the 12S rRNA type-c) is a 16-amino acid peptide encoded by a small open reading frame within the mitochondrial 12S rRNA gene. Its molecular formula is C100H152N28O29S2, with a molecular weight of 2174.32 g/mol. This peptide has garnered significant attention in metabolic research due to its observed interactions with cellular pathways involved in energy metabolism. Early research on MOTS-c identified its presence in various tissues and its potential involvement in the regulation of glucose and fatty acid metabolism. Studies have indicated that MOTS-c may influence insulin sensitivity and cellular energy utilization, primarily through mechanisms associated with mitochondrial activity. Its unique origin from the mitochondrial genome distinguishes it from nuclear-encoded peptides, suggesting a direct link to mitochondrial function. Investigations into the biochemical properties of MOTS-c have explored its potential to modulate AMP-activated protein kinase (AMPK) signaling, a key regulator of cellular energy balance. This interaction may contribute to its observed effects on metabolic pathways. Research applications for MOTS-c include studies on mitochondrial biogenesis, cellular respiration, and the intricate interplay between mitochondrial function and systemic metabolic homeostasis in controlled laboratory settings.
