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 structure consists of a linear chain of amino acids, contributing to its observed biochemical properties. Initial research has focused on its potential as a mitochondrial signaling molecule, influencing various cellular processes. Historically, the discovery of MOTS-c emerged from efforts to identify novel mitochondrial-encoded peptides with regulatory functions. Its unique origin within the mitochondrial genome distinguishes it from nuclear-encoded peptides and proteins. Subsequent studies have aimed to elucidate its specific mechanisms of action at the cellular and molecular levels. Biochemically, MOTS-c has been implicated in pathways related to glucose metabolism and insulin sensitivity in various in vitro and in vivo models. Its interaction with specific cellular targets and its influence on mitochondrial respiration and energy production are areas of ongoing scientific inquiry. Research applications primarily involve exploring its role in metabolic pathways, cellular stress responses, and mitochondrial biology within controlled laboratory settings.
