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:[http://omim.org/entry/277180 277180]].

Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.[1] [2] [3] [4] [5]
Publication Abstract from PubMed
Cystic fibrosis is a fatal genetic disease, most frequently caused by the retention of the CFTR (cystic fibrosis transmembrane conductance regulator) mutant protein in the endoplasmic reticulum (ER). The binding of the 14-3-3 protein to the CFTR regulatory (R) domain has been found to enhance CFTR trafficking to the plasma membrane. To define the mechanism of action of this protein-protein interaction, we have examined the interaction in vitro. The disordered multiphosphorylated R domain contains nine different 14-3-3 binding motifs. Furthermore, the 14-3-3 protein forms a dimer containing two amphipathic grooves that can potentially bind these phosphorylated motifs. This results in a number of possible binding mechanisms between these two proteins. Using multiple biochemical assays and crystal structures, we show that the interaction between them is governed by two binding sites: The key binding site of CFTR (pS768) occupies one groove of the 14-3-3 dimer, and a weaker, secondary binding site occupies the other binding groove. We show that fusicoccin-A, a natural-product tool compound used in studies of 14-3-3 biology, can stabilize the interaction between 14-3-3 and CFTR by selectively interacting with a secondary binding motif of CFTR (pS753). The stabilization of this interaction stimulates the trafficking of mutant CFTR to the plasma membrane. This definition of the druggability of the 14-3-3-CFTR interface might offer an approach for cystic fibrosis therapeutics.
