GO:0005245,MF,"voltage-gated calcium channel activity","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.",IDA
GO:0005886,CC,"plasma membrane","The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.",IEA
GO:0005891,CC,"voltage-gated calcium channel complex","A protein complex that forms a transmembrane channel through which calcium ions may pass in response to changes in membrane potential.",ISS
GO:0006816,BP,"calcium ion transport","The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.",ISS
GO:0034765,BP,"regulation of ion transmembrane transport","Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.",IEA
GO:0061337,BP,"cardiac conduction","Transfer of an organized electrical impulse across the heart to coordinate the contraction of cardiac muscles. The process begins with generation of an action potential (in the sinoatrial node (SA) in humans) and ends with a change in the rate, frequency, or extent of the contraction of the heart muscles.",TAS
