disease:Defects in CLCNKB are the cause of Bartter syndrome type 3 (BS3) [MIM:607364]; also known as classic Bartter syndrome. It is an autosomal recessive form of often severe intravascular volume depletion due to renal salt-wasting associated with low blood pressure, hypokalemic alkalosis, hypercalciuria, and normal serum magnesium levels.,function: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.,miscellaneous:Compared with CLCNKA/BSND, CLCNKB/BSND is more sensitive to pH and less responsive to Ca(2+).,similarity:Belongs to the chloride channel (TC 2.A.49) family.,similarity:Contains 2 CBS domains.,subunit:Interacts with BSND. Forms heteromers with BSND in the thick ascending limb of Henle and more distal segments.,tissue specificity:Expressed predominantly in the kidney.,
Cell membrane; Multi-pass membrane protein.
Expressed predominantly in the kidney.
