    basic FUNCTION
  • kidney-specific chloride channel that mediates trans-epithelial chloride transport in the thin ascending limb of the Henle loop and in the inner medulla
  • involved in the renal concentration function
  • important for maintenance of the corticomedullary osmotic gradient and the kidney capacity to concentrate urine
