Gene

• Entrez ID: 1187
• Gene name: Chloride voltage-gated channel Ka
• Gene symbol: CLCNKA
• Synonyms (NCBI Gene): CLCK1, ClC-K1, hClC-Ka
• Chromosome: 1
• Chromosome location: 1p36.13
• Summary: 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 reabs
