Two distinct regulatory elements were found. The first element is responsible for transcription activation, and the second element provides specific interaction with the promoter of the yellow gene. The findings support the hypothesis of a modular structure for enhancers, including certain sequences that bind transcription activators and special communication elements providing long-distance enhancer-promoter interaction.</p></abstract><trans-abstract xml:lang="ru"><p>Изучена структура нового энхансера En1A из района 1А Х-хромосомы Drosophila melanogaster. В составе En1A картированы элементы, один из которых отвечает за активацию транскрипции, а второй - за специфичное взаимодействие с промотором гена yellow. Полученные данные свидетельствуют в пользу предположения о модульном строении энхансеров, включающих отдельные последовательности, с которыми связываются активаторы транскрипции и особые коммуникаторные элементы, обеспечивающие дистанционные энхансер-промоторные взаимодействия.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Drosophila melanogaster</kwd><kwd>long-distance interactions</kwd><kwd>transcription activation</kwd><kwd>enhancer structure</kwd><kwd>yellow gene</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Drosophila melanogaster</kwd><kwd>дистанционные взаимодействия</kwd><kwd>активация транскрипции</kwd><kwd>структура энхансеров</kwd><kwd>ген yellow</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by a grant from the Russian Science Foundation (project No. 14-14-01067).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Российского научного фонда (проект № 14-14-01067).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Erokhin M., Vassetzky Y., Georgiev P., Chetverina D. // Cell Mol.
