Abstract
Measurement of mRNA translation level has heavily relied on quantifying the amount of polysome-associated RNAs, which would not always reflect efficient translation. To address this, we developed ReleAsing Factor Tethered Editing of RNA (RAFTER), which combined the RNA editing enzyme with translation releasing factor to selectively label successfully translated RNAs. The translation level estimated based on RAFTER correlated well with that by Ribo-seq and Polysome-seq, but with a greatly simplified workflow, which enables it for single-cell analysis.
