+== Disease ==
+[https://www.uniprot.org/uniprot/CFTR_HUMAN CFTR_HUMAN] Defects in CFTR are the cause of cystic fibrosis (CF) [MIM:[https://omim.org/entry/219700 219700]; also known as mucoviscidosis. CF is the most common genetic disease in the Caucasian population, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive. CF is a common generalized disorder of exocrine gland function which impairs clearance of secretions in a variety of organs. It is characterized by the triad of chronic bronchopulmonary disease (with recurrent respiratory infections), pancreatic insufficiency (which leads to malabsorption and growth retardation) and elevated sweat electrolytes.<ref>PMID:1695717</ref> <ref>PMID:2236053</ref> <ref>PMID:1710600</ref> <ref>PMID:1284466</ref> <ref>PMID:1284468</ref> <ref>PMID:1284530</ref> <ref>PMID:1284529</ref> <ref>PMID:7680525</ref> <ref>PMID:7683628</ref> <ref>PMID:7683954</ref> <ref>PMID:7505694</ref> <ref>PMID:7504969</ref> <ref>PMID:7522211</ref> <ref>PMID:7513296</ref> <ref>PMID:7525450</ref> <ref>PMID:7520022</ref> <ref>PMID:7524913</ref> <ref>PMID:7524909</ref> <ref>PMID:7517264</ref> <ref>PMID:8081395</ref> <ref>PMID:7544319</ref> <ref>PMID:8522333</ref> <ref>PMID:7537150</ref> <ref>PMID:7541273</ref> <ref>PMID:7581407</ref> <ref>PMID:7543567</ref> <ref>PMID:7541510</ref> <ref>PMID:8800923</ref> <ref>PMID:8829633</ref> <ref>PMID:8723693</ref> <ref>PMID:8723695</ref> <ref>PMID:8956039</ref> <ref>PMID:9101301</ref> <ref>PMID:9222768</ref> <ref>PMID:9375855</ref> <ref>PMID:9401006</ref> <ref>PMID:9443874</ref> <ref>PMID:9521595</ref> <ref>PMID:9921909</ref> <ref>PMID:9736778</ref> <ref>PMID:9482579</ref> <ref>PMID:9554753</ref> <ref>PMID:9452048</ref> <ref>PMID:9452054</ref> <ref>PMID:9452073</ref> <ref>PMID:10094564</ref>   Defects in CFTR are the cause of congenital bilateral absence of the vas deferens (CBAVD) [MIM:[https://omim.org/entry/277180 277180]. CBAVD is an important cause of sterility in men and could represent an incomplete form of cystic fibrosis, as the majority of men suffering from cystic fibrosis lack the vas deferens.<ref>PMID:7529962</ref> <ref>PMID:7539342</ref> <ref>PMID:9067761</ref> <ref>PMID:10651488</ref> [:]

+== Publication Abstract from PubMed ==
+The most common mutation in cystic fibrosis (CF) patients is deletion of F508 (DeltaF508) in the first nucleotide binding domain (NBD1) of the CF transmembrane conductance regulator (CFTR). DeltaF508 causes a decrease in the trafficking of CFTR to the cell surface and reduces the thermal stability of isolated NBD1; it is well established that both of these effects can be rescued by additional revertant mutations in NBD1. The current paradigm in CF small molecule drug discovery is that, like revertant mutations, a path may exist to DeltaF508 CFTR correction through a small molecule chaperone binding to NBD1. We, therefore, set out to find small molecule binders of NBD1 and test whether it is possible to develop these molecules into potent binders that increase CFTR trafficking in CF-patient-derived human bronchial epithelial cells. Several fragments were identified that bind NBD1 at either the CFFT-001 site or the BIA site. However, repeated attempts to improve the affinity of these fragments resulted in only modest gains. Although these results cannot prove that there is no possibility of finding a high-affinity small molecule binder of NBD1, they are discouraging and lead us to hypothesize that the nature of these two binding sites, and isolated NBD1 itself, may not contain the features needed to build high-affinity interactions. Future work in this area may, therefore, require constructs including other domains of CFTR in addition to NBD1, if high-affinity small molecule binding is to be achieved.
