Вовлечённость белков Ерас как в регуляцию физиологических функций организма, так и в инициации различных патологических процессов позволяет рассматривать их как принципиально новую биомишень для создания оригинальных, высокоэффективных лекарственных средств. Собраны сведения о существующих агонистах и антагонистах белков Ерас, проанализировано влияние строения лигандов Ерас на значения их аффинности и селективности. Представлены предполагаемые механизмы взаимодействия лигандов с белками Ерас.</p></abstract><trans-abstract xml:lang="en"><p>The review discusses modern views about the structure and functions of Epac proteins (exchange proteins directly activated by cyclic adenosine monophosphate). The involvement of Epac proteins both in the regulation of the physiological functions of the body and in the initiation of various pathological processes allows to consider them as a fundamentally new biological target for creating original, highly effective drugs. Information on existing Epac protein agonists and antagonists was collected, and the influence of Epac ligands structure on the values of their affinity and selectivity was analyzed. Presumptive mechanisms of the interaction of ligands with Epac proteins are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>белки Ерас</kwd><kwd>Ерас1</kwd><kwd>Ерас2</kwd><kwd>агонисты Ерас</kwd><kwd>антагонисты Ерас</kwd><kwd>сАМР</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Epac proteins</kwd><kwd>Epac1</kwd><kwd>Epac2</kwd><kwd>Epac agonists</kwd><kwd>Epac antagonists</kwd><kwd>cAMP</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">Kawasaki H, Springett GM, Mochizuki N, et al.
