SARS-CoV-2 NSP1 induces mRNA cleavages on the ribosome

Abstract excerpt

In severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the non-structural protein NSP1 inhibits translation of host mRNAs by binding to the mRNA entry channel of the ribosome and, together with the 5'-untranslated region (UTR) of the viral mRNAs, allows the evasion of that inhibition. Here, we show that NSP1 mediates endonucleolytic cleavages of both host and viral mRNAs in the 5'UTR, but with different...
