Comparison

MOTS-c vs Tirzepatide

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, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.

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, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Length and Sequence

MOTS-c is 16 amino acids long, whereas Tirzepatide is longer as it has a length of 39 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. Tirzepatide 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

Tirzepatide

Glucose-dependent insulinotropic polypeptide receptor (GIPR) and GLP-1 receptor (GLP1R) 24
