| - | [[ | + | [[https://www.uniprot.org/uniprot/SCXA_LEIQH SCXA_LEIQH]] Alpha toxins bind voltage-independently at site-3 of sodium channels (Nav) and inhibit the inactivation of the activated channels, thereby blocking neuronal transmission. The dissociation is voltage-dependent. This toxin is active on insects. It is also highly toxic to crustaceans and has a measurable but low toxicity to mice. |
