It is due to different mutations in the cystic fibrosis transmembrane conductance regulator … WebPrevious studies have indicated that ABP2, formed by the Walker A and B motifs of NBD2 and the signature sequence of NBD1, is the site critical for the ATP-dependent opening of CFTR. The G551D mutation in ABP2, the third most common cystic fibrosis-associated mutation, abolishes ATP-dependent gating, resulting in an open probability that is ∼ ...
