Sodium/Calcium exchangers

Calcium ions are used by cells as ubiquitous signalling molecules that control diverse physiological events. Three mammalian gene families control Ca2+ transport across plasma membranes and intracellular compartments (Lytton J, 2007). They are the Na+/Ca2+ exchanger family designated NCX (SLC8) (three members NCX1-3) (Quednau BD et al, 2004), the Na+/Ca2+-K+ exchanger family designated NCKX (SLC24) (five members NCKX1-5) (Schnetkamp PP, 2004) and a Ca2+/cation exchanger (NCKX6, NCLX) whose physiological function remains unclear.
