Members of the SLC24 gene family encode K+-dependent Na+/Ca2+ exchangers (NCKX) that utilize both the inward Na+ and outward K+ gradients to extrude Ca2+ from cells. There are five human SLC24 genes that play a role in biological process as diverse as vision in retinal rod and cone photoreceptors, olfaction, skin pigmentation and at least three of the five genes are also widely expressed in the brain. Here I review the functional, physiological and structural features of NCKX proteins that have emerged in the past few years.
