Structural highlights
Disease
CLCKA_HUMAN Defects in CLCNKA are a cause of Bartter syndrome type 4B (BS4B) [MIM:613090. A digenic, recessive disorder characterized by impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and varying degrees of hypercalciuria. Bartter syndrome type 4B is associated with sensorineural deafness.[1] [2]
Function
CLCKA_HUMAN Voltage-gated chloride channel. Chloride channels have several functions including the regulation of cell volume; membrane potential stabilization, signal transduction and transepithelial transport. May be important in urinary concentrating mechanisms.
