Cystic Fibrosis Transmembrane Conductance Regulator
Description The cystic fibrosis transmembrane regulator (CFTR) gene codes for the CFTR protein; a chloride channel protein that helps in the transportation of chloride ions and water molecules across the cell membranes of lungs, liver, pancreas, and skin. CFTR is a member of the ATP-binding cassette family of membrane transport proteins, but appears to be unique within this family by functionin...
متن کاملCystic Fibrosis Transmembrane Conductance Regulator
The cystic fibrosis transmembrane conductance regulator (CFTR) Cl channel exhibits lyotropic anion selectivity. Anions that are more readily dehydrated than Cl exhibit permeability ratios (P(S)/P(Cl)) greater than unity and also bind more tightly in the channel. We compared the selectivity of CFTR to that of a synthetic anion-selective membrane [poly(vinyl chloride)-tridodecylmethylammonium chl...
متن کاملStructure and function of the cystic fibrosis transmembrane conductance regulator.
Cystic fibrosis (CF) is a lethal autosomal recessive genetic disease caused by mutations in the CF transmembrane conductance regulator (CFTR). Mutations in the CFTR gene may result in a defective processing of its protein and alter the function and regulation of this channel. Mutations are associated with different symptoms, including pancreatic insufficiency, bile duct obstruction, infertility...
متن کاملThe Cystic Fibrosis Transmembrane Conductance Regulator (CFTR)
Cystic fibrosis affects about 1 in 2500 live births and involves loss of transmembrane chloride flux due to a lack of a membrane protein channel termed the cystic fibrosis transmembrane conductance regulator (CFTR). We have studied CFTR structure by electron crystallography. The data were compared with existing structures of other ATP-binding cassette transporters. The protein was crystallized ...
متن کاملLocalization of Cystic Fibrosis Transmembrane Conductance Regulator
We have used in situ hybridization to localize expression of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in the human gastrointestinal tract and associated organs. The stomach exhibits a low level ofCFTR expression throughout gastric mucosa. In the small intestine, expression is relatively high in the mucosal epithelium, with a decreasing gradient of expression along the...
