[[http://www.uniprot.org/uniprot/NXSA_PSSEM NXSA_PSSEM]] Binds with high affinity to muscular nicotinic acetylcholine receptors (nAChRs) and with low affinity to neuronal alpha-7 nAChRs and inhibit acetylcholine from binding to the receptor, thereby impairing neuromuscular transmission. Produces peripheral paralysis by blocking neuromuscular transmission at the postsynaptic site. Blocks the extracellular increase of dopamine evoked by nicotine at 4.2 uM concentrations.<ref>PMID:9305882</ref> <ref>PMID:9840221</ref>
[https://www.uniprot.org/uniprot/3S1EA_LATSE 3S1EA_LATSE] Binds with high affinity to muscular nicotinic acetylcholine receptors (nAChRs) (tested on Torpedo marmorata, Kd=21 uM) and with low affinity to neuronal alpha-7/CHRNA7 nAChRs (tested on chimeric alpha-7/CHRNA7, Kd=0.07 nM) and inhibits acetylcholine from binding to the receptor, thereby impairing neuromuscular transmission (PubMed:7721859). Blocks the extracellular increase of dopamine evoked by nicotine at 4.2 uM concentrations (PubMed:9840221). In vivo, produces peripheral paralysis.<ref>PMID:7721859</ref> <ref>PMID:9305882</ref> <ref>PMID:9840221</ref>
