enzyme regulation:By intracellular calcium ions.,function:Rapidly transports Ca(2+) during excitation-contraction coupling. Ca(2+) is extruded from the cell during relaxation so as to prevent overloading of intracellular stores.,similarity:Belongs to the sodium/potassium/calcium exchanger family. SLC8 subfamily.,similarity:Contains 2 Calx-beta domains.,tissue specificity:Isoform 2 is expressed in brain and skeletal muscle; Isoform 3 is expressed in excitable cells of brain, retina and skeletal muscle; Isoform 4 is expressed in skeletal muscle.,
