Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them. This toxin blocks rat neuronal nAChR alpha-3-beta-2/CHRNA3-CHRNB2 (IC(50)=128.9 nM) and alpha-7/CHRNA7 (IC(50)=1511 nM) (PubMed:29857567). In vivo, intramuscular injection into zebrafish does not produce any effect on the locomotion of zebrafish (PubMed:29857567). Expressed by the venom duct. The cysteine framework is I (CC-C-C). Alpha4/7 pattern. This toxin does not show effect on neuronal nAChR alpha-4-beta-2/CHRNA4-CHRNB2 and on muscular alpha-1-beta-1-gamma-delta (CHRNA1-CHRNB1-CHRNG-CHRND) (when tested at 10 uM). Belongs to the conotoxin A superfamily.
