Expression of many genes is controlled by Polycomb (PcG) and Trithorax (TrxG) group proteins that act through association with chromatin. PcG/TrxG are assembled on the DNA sequences termed PREs (Polycomb Response Elements), the activity of which can be modulated and switched from repression to activation. In this study, we analyzed the influence of transcriptional read-through on PRE activity switch mediated by the yeast activator GAL4. We show that a transcription terminator inserted between the promoter and PRE doesn’t prevent switching of PRE activity from repression to activation. We demonstrate that, independently of PRE orientation, high levels of transcription fail to dislodge PcG/TrxG proteins from PRE in the absence of a terminator. Thus, transcription is not the main factor required for PRE activity switch.</p></abstract><trans-abstract xml:lang="ru"><p>Поддержание индивидуальных профилей экспрессии генов в клетках разного типа необходимо для дифференцировки и развития многоклеточных организмов. Экспрессия многих генов контролируется белками групп Polycomb (PcG) и Trithorax (TrxG), которые действуют посредством ассоциации с хроматином. Мишенями PcG/TrxG-факторов являются ДНК-элементы, названные PRE (Polycomb Response Elements), активность которых можно модулировать, переключая их с репрессии на активацию. В данной работе проанализировано влияние проходящей транскрипции на переключение активности PRE, опосредованное дрожжевым активатором транскрипции GAL4. Показано, что терминатор транскрипции, встроенный между промотором и PRE-элементом, не препятствует переключению PRE с репрессии на активацию. Вне зависимости от ориентации PRE сильная транскрипция в отсутствие терминатора не приводит к удалению белков PcG/TrxG с PRE. Таким образом, транскрипция не имеет определяющего значения в переключении активности PRE.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Polycomb</kwd><kwd>Trithorax</kwd><kwd>PRE</kwd><kwd>Drosophila</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Polycomb</kwd><kwd>Trithorax</kwd><kwd>PRE</kwd><kwd>Drosophila</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was performed using equipment from the Center of Collective Use at the Institute of Gene Biology RAS.
