CFTR and cystic fibrosis: Alongside the previous study on mapping of the F508del‐CFTR interactome using a deep proteomic analysis method (CoPIT)(Pankow et al, 2015), the results shown in this work represent one of the largest interactome studies of the wt‐CFTR and F508del‐CFTR proteins and should be a valuable resource for CF research.
