Tissue Specificity Expressed in the respiratory airway, including bronchial epithelium, and in the female reproductive tract, including oviduct (at protein level). Detected in pancreatic intercalated ducts in the exocrine tissue, on epithelial cells in intralobular striated ducts in sublingual salivary glands, on apical membranes of crypt cells throughout the small and large intestine, and on the reabsorptive duct in eccrine sweat glands. Detected on the equatorial segment of the sperm head (at protein level). Detected in nasal and bronchial superficial epithelium. Expressed by the central cells on the sebaceous glands, dermal adipocytes and, at lower levels, by epithelial cells.
Post Translational Modifications N-glycosylated. Phosphorylated.cAMP treatment promotes phosphorylation and activates the channel. Dephosphorylation decreases the ATPase activity (in vitro). Phosphorylation at PKA sites activates the channel. Phosphorylation at PKC sites enhances the response to phosphorylation by PKA. Phosphorylated by AMPK.this inhibits channel activity. Ubiquitinated, leading to its degradation in the lysosome. Deubiquitination by USP10 in early endosomes enhances its endocytic recycling to the cell membrane. Ubiquitinated by RNF185 during ER stress. Ubiquitinated by MARCHF2.
Function Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis. Mediates the transport of chloride ions across the cell membrane. Channel activity is coupled to ATP hydrolysis. The ion channel is also permeable to HCO(3)(-).selectivity depends on the extracellular chloride concentration. Exerts its function also by modulating the activity of other ion channels and transporters. Plays an important role in airway fluid homeostasis. Contributes to the regulation of the pH and the ion content of the airway surface fluid layer and thereby plays an important role in defense against pathogens. Modulates the activity of the epithelial sodium channel (ENaC) complex, in part by regulating the cell surface expression of the ENaC complex. Inhibits the activity of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G. Inhibits the activity of the ENaC channel containing subunits SCNN1D, SCNN1B and SCNN1G, but not of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the transporter SLC4A7. Can inhibit the chloride channel activity of ANO1. Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation.
