Neurotoxin
FUNCTION: Insecticidal neurotoxin that induces an irreversible spastic paralysis when injected into insects. Modifies presynaptic voltage-gated sodium channels (Nav), causing them to open at the normal resting potential of the nerve. This leads to spontaneous release of neurotransmitter and repetitive action potentials in motor neurons. {ECO:0000269|PubMed:2914898}.
