Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis (PubMed:26823428). Mediates the transport of chloride ions across the cell membrane (PubMed:20231442, PubMed:22265409). Channel activity is coupled to ATP hydrolysis. The ion channel is also permeable to HCO3-; selectivity depends on the extracellular chloride concentration. Exerts its function also by modulating the activity of other ion channels and transporters. Contributes to the regulation of the pH and the ion content of the epithelial fluid layer. Modulates the activity of the epithelial sodium channel (ENaC) complex, in part by regulating the cell surface expression of the ENaC complex. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the transporter SLC4A7. Can inhibit the chloride channel activity of ANO1 (By similarity). Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation (PubMed:21976599).By similarity5 Publications

Mice are born at the expected Mendelian rate, but about 80% die within two to five days after birth due to peritonitis (PubMed:7685652). Those that survive fail to thrive, appear runted and weigh about half as much as wild-type littermates (PubMed:7685652). Many of the surviving pups die when they start ingesting solid food, due to intestinal blockage caused by excessive mucus accumulation (PubMed:7685652). None survive for more than about 45 days after birth (PubMed:7685652). Intestinal crypts in the jejunum and ileum are filled with excessive mucus (PubMed:7685652). Excessive accumulation of mucus is also seen in colon (PubMed:7685652). In contrast, their lungs do not present pathological mucus accumulation (PubMed:7685652). Likewise, only five out of ten animals show dilatation and blockage of several small pancreatic ducts (PubMed:7685652). Besides, mutant mice present defects in their lacrimal glands that make them more susceptible to develop eye infections (PubMed:7685652). In caecum epithelium, forskolin-sensitive ion transport is nearly abolished (PubMed:7685652).1 Publication

N-glycosylated.By similarity
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.By similarity
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.By similarity

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
