μ-Conotoxins (μ-CTX) are potent Na channel inhibitory peptides isolated from the venom of the predatory marine snail Conus geographus. μ-CTXs exert their biological action by physically occluding the ion-conducting pore of voltage-gated Na (Nav) channels with a 1:1 stoichiometry in an all-or-none fashion. This article reviews our current knowledge of the mechanism of μ-CTX and the associated structural and functional insights into its molecular target - Nav channels.
