A set of proteins (including SNAP-25, VAMP, and syntaxin) that mediate the fusion of neurotransmitter vesicles with the cell membrane, enabling neurotransmitter release. Botox and the cosmetic peptide SNAP-8 work by inhibiting SNARE complex assembly, reducing muscle contraction.
"SNARE Complex" is filed under Signaling Pathways in the PeptideAtlas glossary, alongside 7 other terms in that group.
The term applies directly to 2 compound profiles here: Argireline (evidence F), Snap-8 (evidence F). Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
A protein complex that controls transcription of inflammatory genes. When activated, NF-κB drives production of pro-inflammatory cytokines. Several peptides (KPV, BPC-157, Thymosin Alpha-1) are studied for their ability to inhibit NF-κB, reducing inflammation.
A central intracellular signaling cascade that regulates cell growth, metabolism, survival, and protein synthesis. Activated by growth factors including IGF-1 and insulin. Many anabolic and growth-promoting peptides exert effects through this pathway. mTOR inhibition (e.g., by rapamycin) is a separate longevity research strategy.
A cellular energy sensor activated when ATP levels are low (e.g., during exercise or fasting). AMPK activation promotes glucose uptake, fatty acid oxidation, mitochondrial biogenesis, and autophagy. AICAR (a nucleoside analog, not a peptide) activates AMPK indirectly via its intracellular metabolite ZMP; the mitochondrial-derived peptide MOTS-c also activates AMPK signaling.
Compounds where this applies: Argireline, Snap-8.
