WebThe 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. WebThe gene sequence was identified in 1989 (Rommens et al, 1989; Riordan et al, 1989; Kerem et al, 1989) and shown to encode a 1480 amino acid protein, which has been named the cystic fibrosis transmembrane conductance regulator or, for short, CFTR. (If you imagine the CFTR protein as a long line of bricks, then each amino acid is a single brick. thin summer jacket

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. … WebHisP is a "conserved subunit" of a family of proteins known as ATP-binding cassette (ABC) transporters.
