Should I Stay or Should I Go: eIF3 Remains Ribosome Associated and Is Required for Elongation.

Wagner et al. (2020), Bohlen et al. (2020), and Lin et al. (2020) use Sel-TCP-seq or selective ribosome profiling to gain insights into mRNA translation initiation, highlighting distinctions between yeast and higher eukaryotes and a role for eIF3 in elongation.
