Protein name: NCKX1 Aliases: RODX, HsT17412, KIAA0702 Substrates: Na+, Ca2+, K+ Transport type: Exchanger / 4 Na+, Ca2+, K+ Tissue and cellular expression: rod photoreceptors, platelets Subcellular expression: plasma membrane Disease: congenital stationary night blindness Locus: 15q22 Sequence ID: NP_004718.1, NM_004727.2 Gene ID: 9187 Splice variants: N/D


Gene names: SLC24A1, KIAA0702, NCKX1
Protein names and data: NCKX1_HUMAN, Full=Sodium/potassium/calcium exchanger 1, Full=Na(+)/K(+)/Ca(2+)-exchange protein 1;Full=Retinal rod Na-Ca+K exchanger; Length: 1099 a.a., Mass: 121374 Da,
fasta formatted sequence

Function: Critical component of the visual transduction cascade, controlling the calcium concentration of outer segments during light and darkness. Light causes a rapid lowering of cytosolic free calcium in the outer segment of both retinal rod and cone photoreceptors and the light-induced lowering of calcium is caused by extrusion via this protein which plays a key role in the process of light adaptation. Transports 1 Ca(2+) and 1 K(+) in exchange for 4 Na(+)
Cellular location: Membrane; Multi-pass membrane protein
Tissue specificity: Expressed in the retina, particularly in the inner segment, outer and inner nuclear layers, and ganglion cell layer
