Protein attributes

Sequence length	973 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Rapidly transports Ca2+ during excitation-contraction coupling. Ca2+ is extruded from the cell during relaxation so as to prevent overloading of intracellular stores. Ref.11
Enzyme regulation	By ATP.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Expressed in cardiac sarcolemma, brain, kidney, liver, pancreas, skeletal muscle, placenta and lung. Ref.11
Sequence similarities	Belongs to the sodium/potassium/calcium exchanger family. SLC8 subfamily. Contains 2 Calx-beta domains.
Sequence caution	The sequence AAH98308.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
