Catalysis of the transmembrane transfer of an ion by a voltage-gated channel. An ion is an atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. Catalysis of the transmembrane transfer of a solute by a channel that opens in response to a specific stimulus. Catalysis of the transfer of an ion from one side of a membrane to the other. Catalysis of energy-independent facilitated diffusion, mediated by passage of a specific solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. Catalysis of the transmembrane transfer of a solute by a channel whose open state is dependent on the voltage across the membrane in which it is embedded. Catalysis of the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion. Catalysis of the transmembrane transfer of an anion by a voltage-gated channel. An anion is a negatively charged ion. Catalysis of facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
