    The accuracy of eukaryotic ribosome translocation relies on eukaryote-specific elements of the 80S ribosome, elongation factor 2 and transfer RNAs, all of which contribute to the maintenance of the messenger RNA reading frame.

    Structural studies of the ribosome-associated endoplasmic reticulum translocon complex based on cryo-electron tomography and molecular modelling reveal multiple intermediate states and interactions between the components of the complex and its cofactors.

    During nutrient stress, ribosomal protein abundance is regulated primarily by translational and non-autophagic degradative mechanisms, but ribosome density per cell is largely maintained by reductions in cell volume and rates of cell division.

    All eukaryotes utilize a single termination factor, eRF1, to halt translation when the ribosome encounters one of three possible stop codons; here electron cryo-microscopy structures of ribosome–eRF1 complexes in the process of recognizing each stop codon reveal how stop codons are discriminated from sense codons.

    The structure of the human ribosome at high resolution has been solved; by combining single-particle cryo-EM and atomic model building, local resolution of 2.9 Å was achieved within the most stable areas of the structure.

    The initiation of protein synthesis requires the eukaryotic translation initiation factor (eIF) 2, which uses energy from the hydrolysis of GTP. Another factor, eIF5, accelerates the GTP-hydrolysing activity of eIF2. Here, two other roles for eIF5 have been defined. One involves stabilizing GDP, the product of GTP hydrolysis, on eIF2. In its other role, eIF5 works with phosphorylated eIF2 to inhibit the guanine-nucleotide exchange factor eIF2B. These results clarify our understanding of how the initiation of translation is regulated.
