WebJul 29, 2007 · Nature Structural & Molecular Biology - CFTR regulatory region interacts with NBD1 predominantly via multiple transient helices Skip to main content Thank you for visiting nature.com. WebCystic Fibrosis (CF) is the most common lethal monogenic disorder in Caucasians. It is due to different mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), a protein composed of five domains: two nucleotide binding domains (NBD1 and 2), two transmembrane domains (MSD1 and 2) and one regulatory domain (R) [].The mutations …
