[[https://www.uniprot.org/uniprot/NXL1V_BUNMU NXL1V_BUNMU]] Produces peripheral paralysis by blocking neuromuscular transmission at the postsynaptic site. Binds to muscular and neuronal (alpha-7, alpha-8, and alpha-9) nicotinic acetylcholine receptors. [[https://www.uniprot.org/uniprot/ACHA_MOUSE ACHA_MOUSE]] After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
