Comparison

MOTS-c vs Semaglutide

Function

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, Semaglutide is approved for type 2 diabetes and chronic weight management, significantly lowering HbA1c and body weight by modulating incretin pathways232480.

Mechanism

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, Semaglutide is a modified GLP-1(7–37) analog with three key changes—Ala8→Aib, Lys26 acylated with a C18 fatty diacid, and Lys34→Arg—resulting in a long-acting GLP-1 receptor agonist that enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite23647480.

Length and Sequence

MOTS-c is 16 amino acids long, whereas Semaglutide is longer as it has a length of 31 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. Semaglutide is made up of a sequence of sequence data not available in the current dataset.

Receptor

MOTS-c

No dedicated cell-surface receptor has been definitively identified; signaling is primarily described via intracellular AMPK and related metabolic pathways8135146

Semaglutide

GLP-1 receptor (GLP1R) on pancreatic β-cells and other tissues2380
