WebTwo transmembrane domains (TMD1 and TMD2), two cytoplasmic nucleotide-binding domains (NBD1 and NBD2) and a regulatory (R) domain make up the CFTR protein. Each domain has a special function … Numerous missense mutations that disrupt CFTR folding have been identified within CFTR NBD1 subdomains, including the N-terminal subdomain (L441P and A455E), the N-terminal/α-helical subdomain interface (S492F), and the α-helical subdomain (I507del, F508del, V520F, L558S, A559T, R560K, and R560T)2,45 … See more Three mutations, A455E, L558S, and A559T, demonstrated statistically significant folding disruptions of both α-helical subdomain … See more We next examined the effect of the A455E and L558S on thermal stability of NBD1-folding intermediates by subjecting ribosome-bound nascent polypeptides to progressive thermal … See more We previously demonstrated that the ribosome exerts a destabilizing effect on the nascent polypeptide that transiently delays folding of the α-helical subdomain, thereby keeping it in … See more Finally, we applied a genetic approach to test whether restoring the cotranslational folding pathway was possible, and if so, whether it would correct the final folding outcome and restore … See more

WebThe structure of this chloride ion channel includes two nucleotide-binding domains (NBDs), whose ATPase activity controls channel gating. Recently, the experimental structures of mouse and human CFTR NBD1 and our model of the human CFTR NBD1/NBD2 heterodimer have provided new insights into specific structural features of the CFTR … WebMost patients with cystic fibrosis bear a mutation in the nucleotide-binding domain 1 (NBD1) of CFTR, which plays a key role in the activation of the channel function of CFTR. Determination of the three dimensional structure of NBD1 is essential to better understand its structure-function relationship, and relate it to the biological features ...
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 … WebDec 4, 2009 · The ion channel CFTR contains, in addition to canonical ABC protein domains (TMD1, NBD1, TMD2, NBD2), a unique regulatory (R) domain with multiple cAMP …

W cząsteczce białka CFTR wyróżniamy 12 alfa-helikalnych domen przezbłonowych tworzących kanał, dwie cytoplazmatyczne domeny wiążące nukleotydy (NBD1 i NBD2) oraz domenę regulacyjną R
WebJan 1, 1999 · STE6 is an ABC protein that transports the mating pheromone a-factor across the plasma membrane of yeast. When Teem and co-workers (131 132) replaced part of NBD1 of STE6 with the analogous portion of CFTR NBD1, they found that the chimeric STE6 was still capable of transporting a-factor. Second, it is the MSDs that appear to …
