5uar, resolution 3.73Å Show:Asymmetric Unit Biological Assembly Structural highlights 5uar is a 1 chain structure with sequence from Danio rerio. This structure supersedes the now removed PDB entry 5tsi. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Electron Microscopy, Resolution 3.73Å Ligands: Experimental data: Check Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function CFTR_DANRE Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis (PubMed:20933420, PubMed:23487313, PubMed:25592226). Mediates the transport of chloride ions across the cell membrane (By similarity). 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. Contributes to the regulation of the pH and the ion content of the epithelial fluid layer (By similarity). Required for normal fluid homeostasis in the gut (PubMed:20933420). Required for normal volume expansion of Kupffer's vesicle during embryonic development and for normal establishment of left-right body patterning (PubMed:23487313, PubMed:26432887). Required for normal resistance to infection by P.aeruginosa strain PA14 and strain SMC573 (PubMed:20732993).[UniProtKB:P13569] See Also ABC transporter 3D structures
