The cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-and protein kinase A (PKA)-regulated Cl – channel and a regulator of other ion channels ( 3, 10, 12) (Fig. 1 ). In normal, non-cystic fibrosis (CF) epithelial cells and in recombinant cells ...
WebThe cystic fibrosis transmembrane conductance regulator (CFTR) protein helps to maintain the balance of salt and water on many surfaces in the body, such as the surface of the lung. The CFTR protein is a particular type of protein called an ion channel. In the lung, the CFTR ion channel moves chloride ions from inside the cell to outside the cell. WebThe cystic fibrosis transmembrane conductance regulator (CFTR) gene in man is controlled by a tightly regulated and weak promoter. The architecture of the CFTR promoter suggests regulatory characteristics that are consistent with the absence of a TATA-like sequence, including the ability to initiate RNA transcription at numerous positions. …
