Webb3 mars 2015 · The production of this machinery called ribosome biogenesis is an extraordinarily complex process involving all three RNA polymerases and >150 non-ribosomal factors that are required for the synthesis, processing, transportation, and assembly of pre-ribosomes ( Fatica and Tollervey, 2002; Tschochner and Hurt, 2003 ). Webb16 mars 2024 · peptide continuously repeats the cycle of SRP binding followed by association and dissociation with ER. In contrast with the current view, we show that the long mRNAs remain on the ER while being translated. On the other hand, due to a low ribosome occupancy, the short mRNAs continue the cycle always facing the translation …
