Actions of Genistein on Cystic Fibrosis Transmembrane Conductance Regulator Channel Gating
Previous studies have shown that genistein increased cystic fibrosis transmembrane conductance regulator (CFTR) channel activity in the presence of saturating concentrations of forskolin and calyculin A in intact cells. Possible molecular mechanisms for genistein's action include inhibition of tyrosine kinases, inhibition of serine/threonine protein phosphatases, or direct binding of genistein ...

متن کاملATP hydrolysis-driven gating in cystic fibrosis transmembrane conductance regulator
Proteins belonging to the ATP-binding cassette superfamily couple ATP binding and hydrolysis at conserved nucleotide-binding domains (NBDs) to diverse cellular functions. Most superfamily members are transporters, while cystic fibrosis transmembrane conductance regulator (CFTR), alone, is an ion channel. Despite this functional difference, recent results have suggested that CFTR shares a common...
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...
