A specific therapy for treating this rare disease is missing, due to the lack of knowledge of the molecular mechanisms responsible for its pathogenesis. Starting from the observation that SBDS single-point mutations, localized in different domains of the proteins, are responsible for an SDS phenotype, we carried out the first comparative Molecular Dynamics simulations on three SBDS mutants, namely R19Q, R126T and I212T. The obtained 450-ns long trajectories were compared with those returned by both the open and closed forms of wild type SBDS and strongly indicated that two distinct conformations (open and closed) are both necessary for the proper SBDS function, in full agreement with recent experimental observations. Our study supports the hypothesis that the SBDS function is governed by an allosteric mechanism involving domains I and III and provides new insights into SDS pathogenesis, thus offering a possible starting point for a specific therapeutic option.<\/jats:p>","DOI":"10.3390\/ijms23147938","type":"journal-article","created":{"date-parts":[[2022,7,19]],"date-time":"2022-07-19T05:37:53Z","timestamp":1658209073000},"page":"7938","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Comparative Molecular Dynamics Study of Selected Point Mutations in the Shwachman\u2013Bodian\u2013Diamond Syndrome Protein SBDS"],"prefix":"10.3390","volume":"23","author":[{"given":"Elena","family":"Spinetti","sequence":"first","affiliation":[{"name":"Department of Physics, Trento Institute for Fundamental Physics and Applications, Frankfurt Institute for Advanced Studies, Ruth-Moufang-Stra\u00dfe 1, 60438 Frankfurt am Main, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pietro","family":"Delre","sequence":"additional","affiliation":[{"name":"Institute of Crystallography, National Research Council of Italy, Via Amendola, 122\/o, 70126 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5086-2459","authenticated-orcid":false,"given":"Michele","family":"Saviano","sequence":"additional","affiliation":[{"name":"Institute of Crystallography, National Research Council of Italy, Via Vivaldi, 43, 81100 Caserta, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1415-8725","authenticated-orcid":false,"given":"Dritan","family":"Siliqi","sequence":"additional","affiliation":[{"name":"Institute of Crystallography, National Research Council of Italy, Via Amendola, 122\/o, 70126 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gianluca","family":"Lattanzi","sequence":"additional","affiliation":[{"name":"Department of Physics, Trento Institute for Fundamental Physics and Applications, Frankfurt Institute for Advanced Studies, Ruth-Moufang-Stra\u00dfe 1, 60438 Frankfurt am Main, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4042-2841","authenticated-orcid":false,"given":"Giuseppe Felice","family":"Mangiatordi","sequence":"additional","affiliation":[{"name":"Institute of Crystallography, National Research Council of Italy, Via Amendola, 122\/o, 70126 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1111\/j.1749-6632.2011.06349.x","article-title":"Draft Consensus Guidelines for Diagnosis and Treatment of Shwachman-Diamond Syndrome","volume":"1242","author":"Dror","year":"2011","journal-title":"Ann.
