Comparison
While MOTS-c improves insulin sensitivity, enhances glycolysis, reduces oxidative stress, and shows protective effects in models of metabolic syndrome, aging, and ischemia-reperfusion injury8135146, SS-31 improves mitochondrial bioenergetics, reduces oxidative stress, and shows protective effects in models of ischemia-reperfusion, neurodegeneration, and other mitochondrial disorders4637137.
While MOTS-c works as a 16-amino-acid mitochondrial-derived peptide that translocates to the nucleus under metabolic stress and regulates glucose and lipid metabolism largely via activation of AMPK and modulation of mTOR and folate-cycle–linked pathways854140146, SS-31 is a mitochondria-targeted tetrapeptide, d-Arg-dimethylTyr-Lys-Phe-NH2, that selectively binds cardiolipin in the inner mitochondrial membrane, stabilizing cristae structure, improving electron transport, and reducing ROS production4637137143.
MOTS-c is 16 amino acids long, whereas SS-31 is shorter as it has a length of 4 amino acids. MOTS-c is made up of a sequence of Methionine, Arginine, Tryptophan, Glutamine, Glutamic acid, Methionine, Glycine, Tyrosine, Isoleucine, Phenylalanine, Tyrosine, Proline, Arginine, Lysine, Leucine, Arginine. SS-31 is made up of a sequence of Arginine, dimethylTyr, Lysine, Phenylalanine.
