Filamins Tether Cystic Fibrosis Protein To Cell Surface

... Cystic fibrosis (CF) is caused by mutations in a gene that encodes a protein known as CFTR. More than 1000 different disease-causing mutations in CFTR have been identified, and although the overall effect of each mutation is to decrease CFTR expression at the cell surface, it is not known for every one of these mutations what the molecular defect is that causes the decreased cell surface expression of CFTR. ...
