N1-Methylpseudouridine

N¹-Methylpseudouridine is a modified nucleoside used for enhancing mRNA translation. Incorporation of N¹-Methylpseudouridine into mRNA turns off the immune/eIF2α phosphorylation-dependent inhibition of translation, and increases ribosome pausing and density on the mRNA, thus dramatically facilitating the translation process. N¹-Methylpseudouridine outperforms several other modified nucleosides (e.g. 5-Methylcytidine) and corresponding combinations in terms of translation capacity.
