Cardioviruses bind glycyl-tRNA synthetase for mRNA translation
Дата публикации: 16-04-1770 20:00:17
Viruses often use non-standard mechanisms to translate their mRNAs, which makes it possible to suppress the translation of cellular mRNAs and capture the entire cellular translation apparatus for the synthesis of viral proteins. In a paper published in Nucleic Acids Research, the authors from IBCh and colleagues from the Justus Liebig University (Germany) found that picornaviruses from the genus of cardioviruses (for example, encephalomyocarditis virus, EMCV) have two structures similar to glycyl tRNA in the 5’ and 3’ untranslated regions of mRNA. It has been shown that these elements bind glycyl tRNA synthetase (GARS), and this is necessary for efficient translation of viral mRNA. The interaction of the GARS dimer with 5’ and 3'HTO is likely to cause mRNA cyclization.
