The Na+/Ca2+ Exchange Molecule
An overview of the molecular physiology of the Na+/Ca2+ exchanger is presented. This includes information on the variety of exchangers that have been described and their regulatory properties. Molecular insight is most detailed for the cardiac Na+/Ca2+ exchanger (NCX1). Parts of the NCS1 molecule involved in regulation and ion transport have been elucidated, and initial information on the topology and structure is available.
