   <abstract xml:lang="ru">
    <p>Вирусные участки внутренней посадки рибосомы (Internal Ribosome Entry Site, IRES-элементы) участвуют в кэп-независимой инициации трансляции. Существует 4 основных структурно-различимых типа IRES-элементов: тип I (характерен для полиовирусов), тип II (характерен для вируса энцефаломиокардита), тип III (характерен для вируса гепатита А) и тип IV (характерен для вируса паралича сверчка). IRES-элементы пикорнавирусов типов II и IV изучены значительно лучше, чем типов I и III. Они взаимодействуют в основном с каноническими компонентами трансляционного аппарата (такими как эукариотический фактор eIF4G и рибосомная субчастица 40S), и только с ними удалось реконструировать 48S трансляционный комплекс из очищенных компонентов. Для инициации трансляции на IRES-элементах типа I необходимо значительно большее количество специфических мРНК-связывающих белков (IRES trans acting factors, ITAFs). В связи с этим механизм инициации трансляции на IRES-элементах типа I до сих пор неясен. Недавно было показано, что человеческая глицил-тРНК синтетаза стимулирует инициацию трансляции полиовирусов, а так же был определен минимальны участок полиовирусного IRES-элемента, необходимый для связывания человеческой глицил-тРНК синтетазы. В данной работе мы проанализировали структурные особенности участков IRES- элементов других представителей пикорнавирусов, содержащих IRES-элемент типа I.</p>

    <p>Viral internal ribosome entry site (IRES) mediate cap-independent translation initiation. They are classified into 4 major types: type I (typical for poliovirus), type II (typical for entsefalomiokardit virus), type III (typical for hepatitis a virus) and type IV (typical for cricket paralysis virus). Type II and IV picornavirus IRESs studied much better than the type I and III. They interact mainly with the canonical components of the translational machinery (such as eukaryotic ribosomal factor eIF4G and 40S subunit) and only with them managed to reconstruct the 48S translational complex from purified components. For translational initiation on type I IRES must be a much greater number of specific mRNA - binding proteins (IRES trans acting factors, ITAFs). Thus the mechanism of translation initiation on type I IRES is still unclear. Recently it was shown that human glycyl-tRNA synthetase stimulates the translation initiation of poliovirus, and the minimal fragment of poliovirus IRES which is necessary for binding of human glycyl-tRNA synthetase was determined. In this paper we have analyzed different type I picornavirus IRESs.</p>
