Mitochondrial-derived peptide MOTS-c (MT-RNR1)

Regulates insulin sensitivity and metabolic homeostasis. Inhibits the folate cycle, thus reducing de novo purine biosynthesis which leads to the accumulation of the de novo purine synthesis intermediate 5-aminoimidazole-4-carboxamide (AICAR) and the activation of the metabolic regulator 5'-AMP-activated protein kinase (AMPK).

Protects against age-dependent and diet-induced insulin resistance in addition to diet-induced obesity. .
