Transcript-wide m6A methylation defines the efficiency of cap-independent translation initiation
Here, we combined ribosome profiling under conditions of mTOR inhibition and m⁶A mapping to identify distinct subsets of mRNAs that differ in their sensitivity to the suppression of cap-dependent initiation.
