In this study we report on the ability of the recombinant phototoxic protein DARPin-miniSOG to interact with breast adenacarcinoma human cells overexpressing the extracellular domain of human epidermal growth factor receptor 2 (HER2). It was found that the targeted phototoxin DARPin-miniSOG specifically binds to the HER2 with following internalization and slow recycling back to the cell membrane. An insight into the role of DARPin-miniSOG in HER2 internalization could contribute to the treatment of HER2-positive cancer using this phototoxic protein.</p></abstract><trans-abstract xml:lang="ru"><p>Разработка и исследование новых высокоаффинных белковых соединений, способных избирательно и эффективно уничтожать раковые клетки человека, являются актуальной задачей современных биомедицинских исследований. В работе изучена способность рекомбинантного фототоксичного белка DARPin-miniSOG взаимодействовать с клетками аденокарциномы молочной железы человека, гиперэкспрессирующими рецептор 2 эпидермального фактора роста человека (HER2). Установлено, что адресный фототоксин DARPin-miniSOG специфически взаимодействует с рецептором HER2 и вызывает его интернализацию, за которой следует медленный возврат рецептора на клеточную мембрану. Выяснение характера взаимодействия белка DARPin-miniSOG с рецептором является важным условием для дальнейшей разработки методов воздействия на HER2-положительные опухоли с использованием данного фототоксина.</p></trans-abstract><kwd-group xml:lang="en"><kwd>internalization</kwd><kwd>recycling</kwd><kwd>scaffold proteins</kwd><kwd>DARPin</kwd><kwd>targeted phototoxic protein</kwd><kwd>HER2</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>адресные фототоксичные белки</kwd><kwd>интернализация</kwd><kwd>каркасные белки</kwd><kwd>рециркуляция</kwd><kwd>рецептор HER2</kwd><kwd>DARPin</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation (grant No. 14-24-00106).</funding-statement><funding-statement xml:lang="ru">Работа поддержана Российским научным фондом (грант № 14-24-00106).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Deyev S.M., Lebedenko E.N. // Acta Naturae. 2009, V.1, №1, P.32-50</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Deyev S.M., Lebedenko E.N. // Bioessays. 2008, V.30, №9, P.904-918</mixed-citation></ref><ref id="B3"><label>3.</label><mixed-citation>[3] Boersma Y.L., Plückthun A. // Curr.
