WebNov 30, 2010 · In the vast majority of cystic fibrosis (CF) patients, deletion of residue F508 from CFTR is the cause of disease. F508 resides in the first nucleotide binding domain (NBD1) and its absence leads to CFTR misfolding and degradation. We show here that the primary folding defect arises during synthesis, as soon as NBD1 is translated. … drosophila projectWebThe CFTR gene is expressed in a tissue-specific manner, but the promoter of the gene does not contain any elements that would restrict expression to a subset of tissues. drosophila rna bioanalyzerWebCystic fibrosis (CF) patients develop a severe form of the disease when the cystic fibrosis transmembrane conductance regulator (CFTR) gene is affected by nonsense mutations.
