exocytosis

Antagonist of formyl peptide receptor 1 (FPR1). Reduces superoxide production induced by fMLF with an EC50 of 0.63 μM. Almost completely blocks fMLF-stimulated primary granule exocytosis.

This amino acids187 to 203 fragment is derived from the C-terminal helix of synaptosomal-associated protein of 25 kDa (SNAP-25). This peptide is able to rescue exocytosis from botulinum neurotoxin E (BoNT/E)-treated cells, albeit at higher concentrations

TAT-NSF700scr comprises the complete TAT domain and a glycine linker, succeeded by the NSF amino acids arranged randomly. It serves as a control peptide, ineffective in inhibiting SNARE-mediated exocytosis [1] [2].

ω-Agatoxin IVA TFA is a potent selective inhibitor of P Q type Ca2+ (Cav2.1) channels, with IC50 values of 2 nM for P-type and 90 nM for Q-type channels. It effectively inhibits glutamate exocytosis and calcium influx induced by high potassium, with IC50 values ranging from 30 to 225 nM. Additionally, it blocks high potassium-induced serotonin and norepinephrine release, without impacting L-type or N-type calcium channels [1][2].

TAT-NSF222 Fusion Peptide is a bifunctional polypeptide comprising a TAT domain for cellular uptake via macropinocytosis and an NSF domain that inhibits N-ethylmaleimide-sensitive factor (NSF), serving as an exocytosis inhibitor [1].
