Activity

Neurotoxin
FUNCTION: Beta toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing (By similarity). This toxin is active against mammals and crustaceans. {ECO:0000250}.

Target

voltage-gated sodium channel (Nav)
