Специфические функции и молекулярные механизмы действия этого белка изучены недостаточно. Разработка надежного протокола получения PARP3 с высокой чистотой и выходом представляет собой необходимое условие для всестороннего анализа белка, в том числе изучения его связывания с ДНК, ферментативной активности, взаимодействий с другими белковыми факторами, а также структурных исследований. В данной работе представлен модифицированный протокол экспрессии белка PARP3 человека в клетках Escherichia coli и его последующей очистки, позволяющий существенно увеличить выход белка по сравнению с ранее опубликованными методиками.</p></abstract><trans-abstract xml:lang="en"><p>PARP3 (Poly(ADP-ribose) polymerase 3), like other PARP family members (PARP1 and PARP2), is an important factor in DNA repair. The specific functions and molecular mechanisms of action of this protein remain insufficiently studied. The development of a reliable protocol for obtaining high-purity and yield PARP3 is essential for comprehensive protein analysis, enzymatic activity, including studies of its binding to DNA, interactions with other protein factors, and structural investigations. In this study, we present a modified protocol for the expression of human PARP3 from Escherichia coli cells and its subsequent purification, which significantly increases protein yield compared to previously published methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>PARP3</kwd><kwd>рекомбинантный белок</kwd><kwd>очистка белка</kwd><kwd>Ni2+-сефароза</kwd><kwd>гепаринсефароза</kwd><kwd>хроматография</kwd><kwd>E. coli</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PARP3</kwd><kwd>recombinant protein</kwd><kwd>protein purification</kwd><kwd>Ni2+-sepharose</kwd><kwd>heparin-sepharose</kwd><kwd>chromatography</kwd><kwd>E. coli</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Augustin A., Spenlehauer C., Dumond H., Ménissier-de Murcia J., Piel M., Schmit A.C., Apiou F., Vonesch J.L., Kock M., Bornens M., De Murcia G.
