Here, using a genomic overexpression screen, we have found several genes encoding potentially amyloidogenic proteins, whose overexpression affects the suppressor phenotype in the strain producing the chimeric protein Aβ-Sup35MC on the background of the deletion of SUP35 gene encoding releasing factor eRF 3. It has been demonstrated the NAB2, NAB3 and VTS1 genes participate in the regulation of nonsense-suppression in S. cerevisiae.</p></abstract><trans-abstract xml:lang="ru"><p>Ранее мы показали, что делеция последовательности, кодирующей N-терминальный домен гена SUP35, создает генетический фон, позволяющий выявлять новые гены и эпигенетические детерминанты, контролирующие нонсенссупрессию. В данном исследовании при помощи геномного скрининга мы выявили три гена, кодирующих потенциально амилоидогенные белки, сверхэкспрессия которых влияет на супрессорный фенотип в штамме, продуцирующем химерный белок Aβ-Sup35MC на фоне делеции хромосомной копии гена SUP35, кодирующего фактор терминации трансляции eRF 3. Нами установлено, что гены NAB2, NAB3 и VTS1 участвуют в регуляции нонсенссупрессии у дрожжей S. cerevisiae.</p></trans-abstract><kwd-group xml:lang="en"><kwd>NAB2</kwd><kwd>NAB3</kwd><kwd>VTS1</kwd><kwd>Sup35</kwd><kwd>[NSI+]</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>прион</kwd><kwd>амилоид</kwd><kwd>дрожжи</kwd><kwd>нонсенс-супрессия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Захаров И.
