Summary
Mutations associated with cystic fibrosis (CF) have complex effects on the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common CF mutation, F508del, disrupts the processing to and stability at the plasma membrane and function as a Cl- channel. CFTR is surrounded by a dynamic network of interacting components, referred to as the CFTR Functional Landscape, that impact its synthesis, folding, stability, trafficking and function. CFTR interacting proteins can be manipulated by functional genomic approaches to rescue the trafficking and functional defects characteristic of CF. Here we review recent efforts to elucidate the impact of genetic variation on the ability of the nascent CFTR polypeptide to interact with the proteostatic environment. We also provide an overview of how specific components of this protein network can be modulated to rescue the trafficking and functional defects associated with the F508del variant of CFTR. The identification of novel proteins playing key roles in the processing of CFTR could pave the way for their use as novel therapeutic targets to provide synergistic correction of mutant CFTR for the greater benefit of individuals with CF.
