The DF508 compromises the folding energetics of the NBD1, as well as the folding of three other CFTR domains. Combination of FDA approved corrector molecules can efficiently but incompletely rescue the DF508-CFTR folding and stability defect. Thus, new pharmacophores that would reinstate the wildtype-like conformational stability of the DF508-NBD1 would be highly beneficial. The most prominent molecule, 5-bromoindole-3-acetic acid (BIA) that can thermally stabilize the NBD1 has low potency and efficacy. To gain insights into the NBD1 (un)folding dynamics and BIA binding site localization, we combined molecular dynamics (MD) simulations, atomic force spectroscopy (AFM) and hydrogendeuterium exchange (HDX) experiments. We found that the NBD1 a-subdomain with three adjacent strands from the b-subdomain plays an important role in early folding steps, when crucial non-native interactions are formed via residue F508. Our AFM and HDX experiments showed that BIA associates with this a-core region and increases the resistance of the DF508-NBD1 against mechanical unfolding, a phenomenon that could be exploited in future developments of folding correctors.

An important aspect of transmembrane protein structure is their exact position within the lipid bilayer, a feature hard to investigate experimentally at the atomic level. Here we describe MemBlob, a novel approach utilizing difference electron density maps obtained by cryo-EM studies of transmembrane proteins. The idea behind is that the nonprotein part of such maps carries information on the exact localization of the membrane mimetics used in the experiment and can be used to extract the positional information of the protein within the membrane.

We developed a computational pipeline, where the inputs of a cryo-EM map, the corresponding atomistic structure, and the potential bilayer orientation determined by TMDET algorithm of a given protein result in an output defining the residues assigned to the bulk water phase, lipid interface, and the lipid hydrophobic core. Based on this method, we built a database involving published cryo-EM protein structures and a server to be able to compute this data for newly obtained structures.http://memblob.hegelab.org.Supplementary data are available at Bioinformatics online.}, year = {2020}, eissn = {1460-2059}, pages = {2595-2598}, orcid-numbers = {Farkas, Bianka Vivien/0000-0002-0258-6864; Gáspárné Csizmadia, Georgina/0000-0003-4321-9670; Hegedűs, Tamás/0000-0002-0331-9629} } @article{MTMT:30745347, title = {Discovering the chloride pathway in the CFTR channel}, url = {https://m2.mtmt.hu/api/publication/30745347}, author = {Farkas, Bianka Vivien and Tordai, Hedvig and Padányi, Rita and Tordai, Attila and Gera, János and Paragi, Gábor and Hegedűs, Tamás}, doi = {10.1007/s00018-019-03211-4}, journal-iso = {CELL MOL LIFE SCI}, journal = {CELLULAR AND MOLECULAR LIFE SCIENCES}, volume = {77}, unique-id = {30745347}, issn = {1420-682X}, year = {2020}, eissn = {1420-9071}, pages = {765-778}, orcid-numbers = {Farkas, Bianka Vivien/0000-0002-0258-6864; Tordai, Hedvig/0000-0002-0875-5569; Padányi, Rita/0000-0001-7798-0463; Tordai, Attila/0000-0001-6966-1622; Paragi, Gábor/0000-0001-5408-1748; Hegedűs, Tamás/0000-0002-0331-9629} } @article{MTMT:32499209, title = {Describing the ion passage through the CFTR ion channel}, url = {https://m2.mtmt.hu/api/publication/32499209}, author = {Farkas, Bianka Vivien}, journal-iso = {PHD PROC PPKE IT}, journal = {PHD PROCEEDINGS ANNUAL ISSUES OF THE DOCTORAL SCHOOL FACULTY OF INFORMATION TECHNOLOGY AND BIONICS}, volume = {14}, unique-id = {32499209}, issn = {2064-7271}, year = {2019}, pages = {31}, orcid-numbers = {Farkas, Bianka Vivien/0000-0002-0258-6864} }
