Structure 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 کاملCystic fibrosis transmembrane conductance regulator (ABCC7) structure.
Structural studies of the cystic fibrosis transmembrane conductance regulator (CFTR) are reviewed. Like many membrane proteins, full-length CFTR has proven to be difficult to express and purify, hence much of the structural data available is for the more tractable, independently expressed soluble domains. Therefore, this chapter covers structural data for individual CFTR domains in addition to ...
متن کاملCystic 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 کاملAtomic Structure of the Cystic Fibrosis Transmembrane Conductance Regulator
The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel evolved from the ATP-binding cassette (ABC) transporter family. In this study, we determined the structure of zebrafish CFTR in the absence of ATP by electron cryo-microscopy to 3.7 Å resolution. Human and zebrafish CFTR share 55% sequence identity, and 42 of the 46 cystic-fibrosis-causing missense mutational sit...
