Comparison
While Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141, Snap-8 is a cosmetic peptide studied for reducing wrinkle depth by inhibiting synaptic vesicle fusion and subsequent muscle contraction in facial expression muscles5060.
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, Snap-8 is acetyl octapeptide-3 (Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2), an extended analog of Argireline derived from the N-terminal region of SNAP-25 that competes with native SNAP-25 for binding to syntaxin-1, forming a non-functional SNARE complex and reducing neurotransmitter release5060.
Humanin is 24 amino acids long, whereas Snap-8 is shorter as it has a length of 8 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. Snap-8 is made up of a sequence of Glutamic acid, Glutamic acid, Methionine, Glutamine, Arginine, Arginine, Alanine, Aspartic acid.
