Permeation through the CFTR chloride channel.
The cystic fibrosis transmembrane conductance regulator (CFTR) protein forms a Cl(-) channel found in the plasma membranes of many epithelial cells, including those of the kidney, gut and conducting airways. Mutation of the gene encoding CFTR is the primary defect in cystic fibrosis, a disease that affects approximately 30 000 individuals in the United States alone. Alteration of CFTR function ...
متن کاملPharmacology of CFTR chloride channel activity.
Pharmacology of CFTR Chloride Channel Activity. Physiol. Rev. 79, Suppl.: S109-S144, 1999. - The pharmacology of cystic fibrosis transmembrane conductance regulator (CFTR) is at an early stage of development. Here we attempt to review the status of those compounds that modulate the Cl- channel activity of CFTR. Three classes of compounds, the sulfonylureas, the disulfonic stilbenes, and the ary...
متن کاملRegulation of CFTR chloride channel trafficking by Nedd4-2: role of SGK1
Introduction: The cystic fibrosis transmembrane conductance regulator (CFTR) chloride (Cl−) channel is an essential component of epithelial Cl− transport systems in many organs. CFTR is mainly expressed in the lung and other tissues, such as testis, duodenum, trachea and kidney. The ubiquitin ligase neural precursor cells expressed developmentally down-regulated protein 4-2 (Nedd4-2...
متن کاملStructure and function of the CFTR chloride channel.
Structure and Function of the CFTR Chloride Channel. Physiol. Rev. 79, Suppl.: S23-S45, 1999. - The cystic fibrosis transmembrane conductance regulator (CFTR) is a unique member of the ABC transporter family that forms a novel Cl- channel. It is located predominantly in the apical membrane of epithelia where it mediates transepithelial salt and liquid movement. Dysfunction of CFTR causes the ge...
متن کاملNon-specific activation of the epithelial sodium channel by the CFTR chloride channel.
The genetic disease cystic fibrosis is caused by mutation of the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR). Controversial studies reported regulation of the epithelial sodium channel (ENaC) by CFTR. We found that uptake of (22)Na(+) through ENaC is modulated by activation of CFTR in oocytes, coexpressing CFTR and ENaC, depending on extracellular chloride con...
