It is unknown whether CFTR itself or an associated channel actually transports the ATP. The gene that encodes the CFTR protein, which is also called CFTR, is located on chromosome 7. Therefore, if CFTR is not functional the activity of this channel will be greatly reduced. -, Naehrlich L. The changing face of cystic fibrosis and its implications for screening. Everyone receives one copy of the CFTR gene from each parent. The exocrine pancreas produces enzymes that digest food. Finding small-molecule ligands in cryo-EM protein structures is never a sure thing (at least it isn't in 2022), so being able to pick out the lumacaftor density and work out its interactions with the protein is quite a feat.
