Comparison

Dulaglutide vs Humanin

Function

While Dulaglutide is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite6668, Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141.

Mechanism

While Dulaglutide works as a recombinant fusion protein consisting of two disulfide-linked GLP-1(7–37) analogs each covalently fused via a linker to an IgG4 Fc fragment, yielding a large, long-acting GLP-1 receptor agonist protected from DPP-4 degradation66, Humanin is 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.

Length and Sequence

Dulaglutide is amino acids long, whereas Humanin is longer as it has a length of 24 amino acids. Dulaglutide is made up of a sequence of sequence data not available in the current dataset. 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.

Receptor

Dulaglutide

GLP-1 receptor (GLP1R) 6680

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
