The COVID mRNA vaccines utilize the modified nucleobase N1-methylpseudouridine, in place of canonical uridine, to improve immunogenicity and protein yield. However, relatively few studies have investigated the effect of modified nucleobases on the fidelity of protein translation. Given the interest ...

Given the interest in the COVID mRNA vaccines, we sought to investigate how the RNA modification N1-methylpseudouridine (and its related modification, pseudouridine) is read by ribosomes and reverse transcriptases. By looking at reverse transcriptase data, we can gain information on how the modifica...

The remarkable effectiveness of mRNA vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted synthetic mRNA as a promising technology. A critical feature of this approach is the incorporation of the modified ribonucleotide N1-methylpseudouridine (m¹Ψ), which enh...
