    Transcriptome maps of general eukaryotic RNA degradation factors

    Salma Sohrabi-Jahromi et al.
    Mapping of 30 general RNA degradation factors onto the yeast transcriptome provides the global distribution of factors for RNA turnover and surveillance in a eukaryotic cell.

    Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting

    Jiyu Wang et al.
    An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.

    Codon choice directs constitutive mRNA levels in trypanosomes

    Janaina de Freitas Nascimento et al.
    The information for mRNAs expression level is set by codon choice in trypanosomes and requires translation to be interpreted into a turnover rate.

    Ribosomes slide on lysine-encoding homopolymeric A stretches

    Kristin S Koutmou et al.
    Ribosomes undergo an unanticipated movement (‘sliding’) while translating homopolymeric A sequences, which provides a biochemical rationale for the observation that iterated AAA codons are under-represented in gene-coding sequences.

    eIF1A residues implicated in cancer stabilize translation preinitiation complexes and favor suboptimal initiation sites in yeast

    Pilar Martin-Marcos et al.
    Substitutions in general translation initiation factor eIF1A found as recurring somatic mutations in uveal melanoma destabilize the closed conformation of the preinitiation complex at the start codon and increase discrimination against suboptimal initiation codons genome-wide.

    tRNA genes rapidly change in evolution to meet novel translational demands

    Avihu H Yona et al.
    Experimental evolution and systematic sequence analysis of transfer RNA genes reveal that anticodon mutations provide adaptive plasticity to the translation machinery.

    Systematic bacterialization of yeast genes identifies a near-universally swappable pathway

    Aashiq H Kachroo et al.
    Despite billions of years of divergence, a majority of prokaryotic genes can functionally replace their essential eukaryotic counterparts, revealing broad preservation of ancestral functions and identifying heme biosynthesis as a near-universally swappable pathway.

    Translation affects mRNA stability in a codon-dependent manner in human cells

    Qiushuang Wu et al.
    Genomic-profiles and reporters reveal that the three-nucleotide ‘words’ read by the ribosome, codons, have a strong effect on mRNA stability, impacting the homeostatic mRNA and protein levels in human cells.

    Interface between 40S exit channel protein uS7/Rps5 and eIF2α modulates start codon recognition in vivo

    Jyothsna Visweswaraiah, Alan G Hinnebusch
    The small subunit ribosomal protein uS7/Rps5 interacts with translation initiation factor eIF2α to stabilize first the open, and then the closed conformation of the pre-initiation complex to promote accurate start codon selection in vivo.
