But in this case, loss of a single amino acid in a single protein is enough to lead to a terrible, life-shortening disease, but a small molecule drug - if it binds in just the right place at the right time - is able to tip the thermodynamic balance for that far larger protein over to a state where it has a chance to actually be functional again.

Lung infections that lead to permanent damage are a common problem, and over the years one of the standard treatments, if you can call it that, has been to help clear the airways by flipping the patient head down and beating them on the back with a stick. Cystic fibrosis (CF) is a cruel disease whose genetic cause has been known since the late 1980s. Additional genetic and environmental factors likely play a part in determining the risk of these complex conditions. Vankeerberghen A, Cuppens H, Cassiman JJ. http://www.ncbi.nlm.nih.gov/books/NBK1250/. One in 31 Americans has one CFTR gene mutation. The CFTR protein is a chloride channel, a transport protein that moves chloride ions out of epithelial cells (and whose actions also inhibit the uptake of sodium ions by another such channel). Careers. An official website of the United States government. Physics and Material Science c. Engineering and Biotechnology d. Biotechnology and Mat The CFTR protein is known to acts as a chloride (Cl -) channel expressed in the exocrine glands of several body systems where it also regulates other ion channels, including the epithelial sodium (Na +) channel (ENaC) that plays a key role in salt absorption. Cl- ions are secreted into the mucas, and Na+ ions also build up in the mucas. Structural studies of the cystic fibrosis transmembrane conductance regulator (CFTR) protein are critical to understand molecular mechanisms involved in gating of the apical anion channel as well as the way in which the gating is regulated, especially by the regulatory region (R region).

(That's an object lesson in why knowing the target is not the same as being able to do anything about the disease). Mutations in the CFTR gene disrupt the function of the chloride channel, preventing the usual flow of chloride ions and water into and out of cells. An ion channel moves atoms or molecules that have an electrical charge from inside the cell to outside, or from outside the cell to inside.

When you step back and look at the disease and at these therapies, it's a remarkable picture. The CFTR protein is a particular type of protein called an ion channel. Intracellular CFTR: localization and function. It is unknown whether CFTR itself or an associated channel actually transports the ATP. A change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. 1,2.

This mucus clogs the tubes that carry sperm from the testes (the vas deferens) as they are forming, causing them to deteriorate before birth. 1. Cystic fibrosis is caused by a mutation of the CFTR gene. This leads the mucus covering the cells to become thick and sticky, causing many of the symptoms associated with cystic fibrosis. Mol. Proteins are assembled from building blocks called amino acids. CFTR functions as an ATP-gated, phosphorylation-regulated Cl- channel that mediates agonist-stimulated apical membrane epithelial Cl- and bicarbonate secretion and also regulates a variety of other transport proteins and cellular processes.

This mutation is caused by the deletion of three base pairs of the CFTR gene leading to the loss of an amino acid called phenylalanine, abbreviated F, in the CFTR protein. These conditions include bronchiectasis, which damages the passages leading from the windpipe to the lungs (the bronchi), and allergic bronchopulmonary aspergillosis, which results from hypersensitivity to a certain type of fungal infection. Cuppens H, Cassiman JJ. The chloride channel is an ATP-binding cassette (ABC) transporter and is comprised of three distinct domains or parts, which include two nucleotide-binding domains (NBD 1 and 2), two membrane-spanning . The ASL also contains antiproteases, antioxidants, antibodies and other substances that work together to neutralize or destroy invading organisms without damaging the lungs. 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. This review shows that the CFTR protein is not just a chloride channel. If a CF patient consents to a clinicial trial, what are the aspects of a CF clinicial trial and how would you explain the trial as it is? The CFTR protein reaches the cell surface butchloridetransportthrough the channel is defective. 10.1038/nature04712. Revisiting CFTR Interactions: Old Partners and New Players. Genet Med.

Most people with CF do not make pancreatic enzymes leading to a problem called pancreatic insufficiency. Dysfunction of the CFTR protein affects not only the ion transport across the epithelial tissues, but also has an impact on the proper functioning of the intracellular compartments. As the CFTR channel is an ATP-dependent ion channel, its opening requires R-domain phosphorylation (P) by the protein kinase A (PKA) and ATP binding at the NBDs leading to their dimerization, which in turn allows the chloride (Cl, Schematic representation of ion transport in airway epithelia.
