...Cornelia Kilchert; Lidia Vasiljeva Eukaryotic mRNAs are extensively processed to generate functional transcripts, which are 5′ capped, spliced and 3′ polyadenylated. Accumulation of unprocessed (aberrant) mRNAs can be deleterious for the cell, hence processing fidelity is closely monitored by QC...

.... As expected, synthesis of proteins encoded by mRNAs that contain a 5′-TOP (5′-terminal oligopyrimidine tract) was impaired by rapamycin, but more strongly by mTOR kinase inhibition. Several proteins not known to be encoded by 5′-TOP mRNAs also showed similar behaviour. Synthesis of proteins encoded by ‘non...
