TED-Seq Identifies the Dynamics of Poly(A) Length during ER Stress

Post-transcriptional RNA processing is a core mechanism of gene expression control in cell stress response. The poly(A) tail influences mRNA translation and stability, but it is unclear whether there are global roles of poly(A)-tail lengths in cell stress. To address this, we developed tail-end displacement sequencing (TED-seq) for an efficient transcriptome-wide profiling of poly(A) lengths and applied it to endoplasmic reticulum (ER) stress in...
