This function is crucial to the osmotic balance of the mucus and its View PDF Groman JD, Meyer ME, Wilmott RW, Zeitlin PL, Cutting GR. The majority of cystic fibrosis (CF)-causing mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) lead to the misfolding, mistrafficking, and degradation of the mutant protein. The airways are covered with a thin, layer of liquid called airway surface liquid (ASL) and a mucus gel layer. Respir Res. This sweeping motion moves mucus up and out of the airways. The cystic fibrosis transmembrane conductance regulator (CFTR) is the gene product mutated in cystic fibrosis, a common lethal genetic disease characterized by abnormal electrolyte transport across epithelia. -. The CFTR protein is a large, unique member of the subclass C family of the ATP binding cassette (ABC) transporter proteins, which functions as an ion channel rather than an active transporter protein [ 7, 8, 9 ]. All of these changes prevent the channel from functioning properly, which impairs the transport of chloride ions and the movement of water into and out of cells. nadine_nabil_42778. All proteins are made up of chains of these amino acids connected together in different orders, like different words that are written using the same 26 letters of the alphabet.
