The inherited CF gene directs the body's epithelial cells to produce a defective form of a protein called CFTR (or cystic fibrosis transmembrane conductance regulator) found in cells that line the lungs, digestive tract, sweat glands, and genitourinary system. 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.

For example, CFTR mutations have been found in some cases of idiopathic pancreatitis, an inflammation of the pancreas that causes abdominal pain, nausea, vomiting, and fever. 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. Epithelial tissues are made of one or more layers of cells that cover their surface and are joined to one another by junctional proteins. conductance regulator: an intriguing protein with pleiotropic functions. The high chloride concentration in the sweat can be used to diagnose people with CF.

It is a chronic disease that currently has no cure. 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. In practice, most patients get a dual-therapy regime of both a potentiator and a corrector, and the fact that both of these can work at the same time in patients is not something that anyone could have taken for granted, either.
