Many GPCRs, despite their importance for pharmacology, are still considered orphan, i.e., their endogenous ligand is unknown. Orphan receptor GPR17, belonging to class A GPCR, is expressed mainly in the central nervous system, plays an important role in the formation of the myelin sheath of neurons and is a potential target for the development of new drugs against multiple sclerosis, Alzheimer's disease and ischemia. The aim of this work was to prepare GPR17 for structure-functional studies, starting with the heterologous expression and ending with obtaining a stable protein sample. Screening of various genetically engineered constructs was performed, a number of point mutations were analyzed, and a significant number of potential ligands of this receptor were tested. As a result of the work, the conditions for expression, isolation, and purification of GPR17 were optimized, which together made it possible to obtain a fairly stable and monomeric protein preparation suitable for further structural studies.</p></abstract><trans-abstract xml:lang="ru"><p>Рецепторы, сопряженные с G-белком (GPCR), – это семейство семиспиральных трансмембранных белков, состоящее более чем из 800 представителей в геноме человека, играющих ключевую роль в регуляции большинства процессов в организме и являющихся мишенями для трети всех современных лекарств. Многие GPCR, несмотря на значимость для фармакологии, до сих пор орфанные, т.е. эндогенный лиганд для них неизвестен. Орфанный рецептор GPR17, относящийся к классу А GPCR, экспрессируется преимущественно в центральной нервной системе, играет важную роль в регуляции образования миелиновой оболочки нейронов и представляет собой потенциальную мишень для разработки новых лекарственных препаратов против рассеянного склероза, болезни Альцгеймера и ишемии. Цель данной работы заключалась в подготовке GPR17 для структурно-функциональных исследований, начиная с модификации рецептора и заканчивая получением белкового препарата. Был проведен скрининг различных генно-инженерных конструкций, проанализирован ряд точечных мутаций, а также проверено значительное число потенциальных лигандов данного рецептора. В результате работы оптимизированы условия экспрессии, выделения и очистки GPR17, что в совокупности позволило получить достаточно стабильный и мономерный белковый препарат, подходящий для дальнейших структурных исследований.</p></trans-abstract><kwd-group xml:lang="en"><kwd>GPCR</kwd><kwd>GPR17</kwd><kwd>protein stabilization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>GPCR</kwd><kwd>GPR17</kwd><kwd>стабилизация белка</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>договор 075-03-2024-117, проект № FSMG-2024-0012</award-id></award-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>24-74-10020</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kuneš J., Hojná S., Mráziková L., Montezano A., Touyz R., Maletínská L. // Physiol Res. 2023.
