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. The most common CFTR mutation, present in approximately 70 percent of people with CF, is F508del. CFTR variant Probably the most common is "delta-508", where a phenylalanine residue is skipped entirely. 12;352(19):1992-2001. doi: 10.1056/NEJMra043184. The .gov means its official. HHS Vulnerability Disclosure, Help It consists of two membrane-spanning domains (MBDs) that form the ion channel. This leads to the classic CF phenotype, thickened mucus in the lungs due to the dysfunctional epithelial cells in the airway lining that should be moving it along and clearing it, but can't. This function is crucial to the osmotic balance of the mucus and its viscosity. 1997 Jun 27;109(12-13):457-64.

The CFTR gene provides instructions for making a protein called the CF transmembrane conductance regulator (CFTR). Cuppens H, Cassiman JJ. All of these changes prevent the channel from functioning properly, which impairs the transport of chloride ions and the movement of water into and out of cells. The majority of cystic fibrosis (CF)-causing mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) lead to the misfolding, mistrafficking, and degradation of the mutant protein. Protein B normally stimulates cell division, and the mutation created an overactive version of protein B. .

When a mutation causes an amino acid to be deleted or an incorrect amino acid to be added, the CFTR protein cannot form its correct 3-D shape and function properly. Together, these 3 components target certain CFTR protein defects caused by the F508del mutation or another mutation responsive to TRIKAFTA. By some very nice cryo-EM structural biology work, they show that the binding site is in the transmembrane domain of the channel, and that when a corrector molecule fills this spot it stabilizes four transmembrane helices that are otherwise not energetically favored to stay in the right conformation.

Sinus Disease Grading on Computed Tomography Before and After Modulating Therapy in Adult Patients with Cystic Fibrosis. There are hundreds of known mutations in it, many of which lead to cystic fibrosis of varying severity. While the basolateral membrane is in contact with the interstitial tissue, the apical membrane is in contact with the external environment and thus also acts as a barrier to prevent potential pathogens or toxic compounds from reaching the bloodstream. Groman JD, Meyer ME, Wilmott RW, Zeitlin PL, Cutting GR. Clipboard, Search History, and several other advanced features are temporarily unavailable. However, it is known that the channel is modulated by the P2Y2 receptor which is activated by ATP. Most people with CF do not make pancreatic enzymes leading to a problem called pancreatic insufficiency. The resulting abnormal channel breaks down shortly after it is made, so it never reaches the cell membrane to transport chloride ions. and transmitted securely.

A gated channel protein reacting to a signal molecule can be seen in the image below. When there is less water outside the cells, the mucus in the airways becomes dehydrated and thickens, causing it to flatten the cilia. doi: 10.1093/mp/ssq013. Cl- ions are secreted into the mucas, and Na+ ions also build up in the mucas. The CFTR gene is transcribed into a single strand of RNA within the cell nucleus (2); regions that are not needed to make the protein are spliced out, producing the final messenger RNA (mRNA) (3). Disclaimer. CFTR is an anion channel mainly conducting Cl-across the apical membranes of many different epithelial cells, the impairment of which causes dysregulation of epithelial fluid secretion and thickening of the mucus.
