CONOTOXIN-PeIA
Product ID L8518 
Name CONOTOXIN-PeIA alpha-
Molecular formula C65H98N22O21S4
Description
A 16 amino-acids peptide with 2 disulfide bridges , synthetic, initially isolated from the venom of the Grand cone snail Conus pergrandis.
Biological activity

This synthetic peptide potently and reversibly blocks alpha-9-alpha-10 nAChR (IC50=6.9-54.9 nM), alpha-3-beta-2 (IC50=9.7-97.5 nM) and alpha-6/alpha-3-beta-2-beta-3 (IC50=11.1-17.2 nM) . Also shows a weak inhibition of alpha-6/alpha-3-beta-4 (IC50=147 nM) and alpha-3-beta-4 (IC50=480-1500 nM). Alpha-conotoxin PeIA also inhibits N-type calcium channels (Ca2.2/CACNA1B) (IC50=1.1 nM) via the activation of the G protein-coupled GABA(B) receptor in DRG neurons. Alpha-conotoxin PeIA shows a very weak or no inhibition on muscle alpha-1-beta-1-gamma-delta, neuronal alpha-7, and neuronal alpha-4-beta-2 nAChR.
