The CG9890 binding sites are low-nucleosome-density regions and are colocalized with the chromatin modifying and remodeling complexes SAGA and dSWI/SNF, as well as with the ORC replication complex. The CG9890 protein was shown to be involved in the regulation of the expression of some genes on the promoters of which it is located, with the ecdysone cascade genes accounting for a significant percentage of these genes. Thus, the CG9890 protein is a new member of the transcriptional network which is localized on active promoters, interacts with the main transcription and replication complexes, and is involved in the regulation of both basal and inducible transcription.</p></abstract><trans-abstract xml:lang="ru"><p>Проведено полногеномное исследование белка CG9890, содержащего домены цинковых пальцев. Показано, что белок CG9890 локализован преимущественно на промоторах активных генов. Сайты связывания CG9890 характеризуются низкой плотностью нуклеосом и колокализуются с комплексами модификации и ремоделирования хроматина SAGA и dSWI/SNF, а также с репликационным комплексом ORC. Показано, что белок CG9890 участвует в регуляции экспрессии части генов, на промоторах которых он находится, причем заметную долю этих генов составляют гены экдизонового каскада. Таким образом, белок CG9890 является новым участником транскрипционной сети клетки, локализуется на активных промоторах, взаимодействует с основными транскрипционными и репликационными комплексами и участвует в регуляции как базальной, так и индуцибельной транскрипции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ENY2</kwd><kwd>CG9890</kwd><kwd>Drosophila</kwd><kwd>zinc fingers</kwd><kwd>ChIP-Seq</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ENY2</kwd><kwd>CG9890</kwd><kwd>дрозофила</kwd><kwd>цинковые пальцы</kwd><kwd>ChIP-Seq</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>20-14-00269</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Vorobyeva N.E., Mazina M.U., Golovnin A.K., Kopytova D.V., Gurskiy D.Y., Nabirochkina E.N., Georgieva S.G., Georgiev P.G., Krasnov A.N. // Nucl.
