EOG873S56 GO:0005891 3/30 voltage-gated calcium channel complex cellular_component "A protein complex that forms a transmembrane channel through which calcium ions may pass in response to changes in membrane potential." [GOC:mah] EOG873S56 GO:0005245 3/30 voltage-gated calcium channel activity molecular_function "Enables the transmembrane transfer of a calcium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded." [GOC:mtg_transport, GOC:tb, ISBN:0815340729]
