Activity

Neurotoxin
FUNCTION: Insecticidal neurotoxin that induces irreversible neuromuscular blockade in house crickets (A.domesticus). 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:2298738}.

Target

voltage-gated sodium channel (Nav)
