[https://www.uniprot.org/uniprot/3L21_LATSE 3L21_LATSE] Binds with high affinity to muscular (tested on Torpedo marmorata, Kd=1.6 nM) and neuronal (chimeric alpha-7/CHRNA7, Kd=3 nM) nicotinic acetylcholine receptor (nAChR) and inhibits acetylcholine from binding to the receptor, thereby impairing neuromuscular and neuronal transmission (PubMed:9305882). Also shows a very weak inhibition on GABA(A) receptors (PubMed:26221036). The toxin (10 uM) inhibits 83% of current in channels composed of alpha-1-beta-3-gamma-2 (GABRA1-GABRB3-GABRG2) subunits, 39% of current in channels composed of alpha-2-beta-2-gamma-2 (GABRA2-GABRB2-GABRG2) subunits, and 33% of current in channels composed of alpha-5-beta-2-gamma-2 (GABRA5-GABRB2-GABRG2) subunits (PubMed:26221036).<ref>PMID:26221036</ref> <ref>PMID:9305882</ref>
