Secondary Accession Numbers
| |
Name
| Sodium/potassium/calcium exchanger 1 |
Synonyms
|
- Na(+)/K(+)/Ca(2+)-exchange protein 1
- Retinal rod Na-Ca+K exchanger
|
Gene Name
| SLC24A1 |
Protein Type
| Unknown |
Biological Properties |
General Function
| Involved in calcium, potassium:sodium antiporter activity |
Specific 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(+) |
