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.

GO:0034765

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

BP

GO:0061337

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.

GO:0070588

calcium ion transmembrane transport

A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.

IEA

CC

GO:0005886

plasma membrane

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

TAS

CC

GO:0005891

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.

NAS

MF

GO:0005245

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.
