Ion channels and pumps in cardiac function.
Ion channels and pumps are intrinsic membrane proteins that regulate the membrane potential and transport of ions and substrates, controlling excitation and excitation-contraction coupling. Several have been cloned and an example of our progress in structure-function correlation is the identification of the pore region of the Na channel.
