Summaries for CLCNKA Gene

Entrez Gene Summary for CLCNKA Gene

  • This gene is a member of the CLC family of voltage-gated chloride channels. The encoded protein is predicted to have 12 transmembrane domains, and requires a beta subunit called barttin to form a functional channel. It is thought to function in salt reabsorption in the kidney and potassium recycling in the inner ear. The gene is highly similar to CLCNKB, which is located 10 kb downstream from this gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for CLCNKA Gene

CLCNKA (Chloride Voltage-Gated Channel Ka) is a Protein Coding gene. Diseases associated with CLCNKA include bartter syndrome, type 4b, digenic and diabetes insipidus. Among its related pathways are Diuretics Pathway, Pharmacodynamics and Activation of cAMP-Dependent PKA. GO annotations related to this gene include ion channel activity and voltage-gated chloride channel activity. An important paralog of this gene is CLCN7.

UniProtKB/Swiss-Prot for CLCNKA Gene

  • 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.
