Comparison

Humanin vs Setmelanotide

Function

While Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141, Setmelanotide is approved for chronic weight management in patients with POMC, PCSK1, LEPR deficiencies and Bardet–Biedl syndrome by reducing hunger and promoting weight loss92.

Mechanism

While Humanin works as a mitochondrial-derived 24-amino-acid peptide that protects cells against diverse apoptotic insults by interacting with cell-surface cytokine receptor complexes and intracellular targets, thereby activating pro-survival STAT3 and other pathways7136141, Setmelanotide is a potent synthetic melanocortin-4 receptor (MC4R) agonist derived from a POMC/α-MSH–related sequence that restores downstream MC4R signaling in genetic obesity syndromes3192100.

Length and Sequence

Humanin is 24 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. Humanin is made up of a sequence of Methionine, Alanine, Proline, Arginine, Glycine, Phenylalanine, Serine, Cysteine, Leucine, Leucine, Leucine, Leucine, Leucine, Threonine, Serine, Glutamic acid, Isoleucine, Aspartic acid, Leucine, Proline, Valine, Lysine, Arginine, Arginine, Alanine. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.

Receptor

Humanin

Binds a trimeric cytokine receptor complex consisting of CNTFR, WSX-1, and gp130, and can also signal via the G-protein–coupled receptor FPRL1/FPR2136141
