  • 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.
  • Tissue specificity

    Expressed predominantly in the kidney.
  • Involvement in 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.
    Defects in CLCNKB 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.
  • Sequence similarities

    Belongs to the chloride channel (TC 2.A.49) family. CLCNKB subfamily.
    Contains 2 CBS domains.

  • Paraffin-embedded human breast cancer tissue stained for CLCNKB using ab236733 at 1/300 dilution in immunohistochemical analysis.

    After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30 minutes at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • All lanes : Anti-CLCNKB antibody (ab236733) at 1/500 dilution

    Lane 1 : HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate
    Lane 2 : Rat kidney tissue lysate

    All lanes : Goat polyclonal to rabbit IgG at 1/50000 dilution

    Predicted band size: 75 kDa

  • HepG2 (human liver hepatocellular carcinoma cell line) cells labeling CLCNKB (Green) using ab236733 at 1/100 dilution in ICC/IF, followed by Alexa Fluor® 488-congugated Goat Anti-Rabbit IgG (H+L). Counterstained with DAPI.

    The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum.
