Basic Information
Overview
CLCN4 (Chloride Voltage-Gated Channel 4) is a gene located on chromosome Xp22.2. The encoded protein is a voltage-gated chloride channel involved in cellular ion homeostasis, acidification of intracellular compartments, and neuronal function. CLCN4 mutations are associated with neurodegenerative diseases and lysosomal storage disorders.
Function
The CLCN5 gene encodes ClC-5, a chloride channel essential for renal proximal tubule function. It localizes to endosomes in proximal tubule cells and is critical for endosomal acidification and receptor-mediated endocytosis.
Tissue Distribution
Kidney: High expression in proximal tubules
Intestine: Small intestinal epithelium
Liver: Low expression
Physiological Roles
Renal reabsorption: Critical for proximal tubule endosomal function
Endosomal acidification: Couples chloride flux to proton pumping
Protein reabsorption: Essential for receptor-mediated endocytosis of filtered proteins
Disease Associations
Dent Disease
Mutations: Nonsense and missense mutations causing loss of function
