Regulation of CFTR chloride channel trafficking by Nedd4-2: role of SGK1
Introduction: The cystic fibrosis transmembrane conductance regulator (CFTR) chloride (Cl−) channel is an essential component of epithelial Cl− transport systems in many organs. CFTR is mainly expressed in the lung and other tissues, such as testis, duodenum, trachea and kidney. The ubiquitin ligase neural precursor cells expressed developmentally down-regulated protein 4-2 (Nedd4-2...
متن کاملSplicing of human chloride channel 1
Expression of chloride channel 1 (CLCN1/ClC-1) in skeletal muscle is driven by alternative splicing, a process regulated in part by RNA-binding protein families MBNL and CELF. Aberrant splicing of CLCN1 produces many mRNAs, which were translated into inactive proteins, resulting in myotonia in myotonic dystrophy (DM), a genetic disorder caused by the expansion of a CTG or CCTG repeat. This incr...

متن کاملRegulation of TMEM16A chloride channel properties by alternative splicing.
Expression of TMEM16A protein is associated with the activity of Ca(2+)-activated Cl(-) channels. TMEM16A primary transcript undergoes alternative splicing. thus resulting in the generation of multiple isoforms. We have determined the pattern of splicing and assessed the functional properties of the corresponding TMEM16A variants. We found three alternative exons, 6b, 13, and 15, coding for seg...
متن کاملRegulation of CFTR chloride channel macroscopic conductance by extracellular bicarbonate.
The CFTR contributes to Cl⁻ and HCO₃⁻ transport across epithelial cell apical membranes. The extracellular face of CFTR is exposed to varying concentrations of Cl⁻ and HCO₃⁻ in epithelial tissues, and there is evidence that CFTR is sensitive to changes in extracellular anion concentrations. Here we present functional evidence that extracellular Cl⁻ and HCO₃⁻ regulate anion conduction in open CF...
