Insecticidal neurotoxin. Shows competition for site 3 of insect voltage-gated sodium channels (Nav). Induces flaccid paralysis when injected into lepidopteran larvae. Is not toxic to mice when injected intracranially at 20 pmol/g. Expressed by the venom gland. The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. LD(50) is 17.6 nmol/kg to lepidopteran larvae. Belongs to the neurotoxin 14 (magi-1) family. 09 (magi-1) subfamily.
