CC   -!- FUNCTION: Mu-conotoxins block voltage-gated sodium channels. This toxin
CC       reversibly blocks voltage-gated sodium channel in cephalopods, with no
CC       alteration in the voltage dependence of sodium conductance or on the
CC       kinetics of inactivation (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC   -!- DOMAIN: The cysteine framework is XII (C-C-C-C-CC-C-C).
