   <abstract xml:lang="ru">
    <p>При помощи методов кругового дихроизма и малоуглового рассеяния рентгеновских лучей (SAXS) получены данные о пространственной структуре мультимеризующего N-концевого домена инсуляторного белка CTCF Drosophila melanogaster . По аминокислотной последовательности данный домен не имеет гомологии ни с одним известным белковым доменом. По данным кругового дихроизма N-концевой домен белка CTCF Drosophila практически не имеет вторичной структуры. По данным SAXS этот домен имеет стабильную компактную структуру в растворе и является тетрамером. Получены модели низкого разрешения структуры тетрамера в растворе. Формирование тетрамеров также подтверждается при помощи методов динамического рассеяния света (DLS) и гель-фильтрации.</p>

   <trans-abstract xml:lang="en">
    <p>Spatial structure of N-terminal multimerization domain from Drosophila melanogaster CTCF insulator protein was studied using circular dichroism and small-angle X-ray scattering (SAXS). This domain has no significant homology in amino acid sequence with any other known protein domain. Circular dichroism spectra revealed that N- terminal domain of Drosophila CTCF protein almost completely lacks secondary structure. SAXS data indicated that domain possess a stable compact conformation in solution and exists as a tetramer. Low-resolution models of spatial structure of the tetramer were built. Tetramer formation is also supported by dynamic light scattering (DLS) and size-exclusion chromatography.</p>
