Strict coupling between CFTR’s catalytic cycle and gating of its Cl(−) ion pore revealed by distributions of open channel burst durations

CFTR, the ABC protein defective in cystic fibrosis, functions as an anion channel. Once phosphorylated by protein kinase A, a CFTR channel is opened and closed by events at its two cytosolic nucleotide binding domains (NBDs). Formation of a head-to-tail NBD1/NBD2 heterodimer, by ATP binding in two i...
