Activity

Neurotoxin
FUNCTION: Mu-conotoxins block voltage-gated sodium channels. This toxin reversibly blocks voltage-gated sodium channel in cephalopods, with no alteration in the voltage dependence of sodium conductance or on the kinetics of inactivation (By similarity). {ECO:0000250}.

Target

voltage-gated sodium channel (Nav)
