Neurotoxin
FUNCTION: Competes for binding at site 3 of the insect voltage-gated sodium channel (Nav) (PubMed:12860384). Insecticidal neurotoxin (PubMed:12860384, PubMed:29247580). Causes temporary paralysis to lepidopteran larvae (10.3 nmol/g) or to crickets (doses from 0.93 to 119 ug/g) (PubMed:12860384, PubMed:29247580). Is not toxic to mice when injected intracranially (high doses) (PubMed:12860384, PubMed:29247580). {ECO:0000269|PubMed:12860384, ECO:0000269|PubMed:29247580}.
