    Homologene
    FAMILY chloride channel Kb family
    CATEGORY transport channel
    SUBCELLULAR LOCALIZATION     plasma membrane
    text basolateral membrane of the thick ascending limb of Henle loop
    basic FUNCTION
  • participating in renal NaCl reabsorption
  • reclaiming most of the chloride that is left in the urine
  • may be important in urinary concentrating mechanisms
  • key determinant of tubular reabsorption of chloride and electrolytes along the distal tubule
  • plays a major role in the absorption of NaCl in the distal nephron
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS excretion
    PATHWAY
    metabolism
    signaling
    a component heterodimerizing with Barttin (BSND)
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to BSND
  • require the accessory subunit barttin for proper function and membrane insertion
  • cell & other
