    Kinetics of initiating polypeptide elongation in an IRES-dependent system

    Haibo Zhang et al.
    The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.

    Pharmacological dimerization and activation of the exchange factor eIF2B antagonizes the integrated stress response

    Carmela Sidrauski et al.
    A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

    Ssd1 and Gcn2 suppress global translation efficiency in replicatively aged yeast while their activation extends lifespan

    Zheng Hu et al.
    Activation of the stress response pathway in young cells extends replicative lifespan, not by reducing global protein synthesis per se, but by Gcn4-mediated autophagy induction.

    Poly(A) tail length regulates PABPC1 expression to tune translation in the heart

    Sandip Chorghade et al.
    A poly(A) tail-based regulatory mechanism dynamically controls PABPC1 protein synthesis in cardiomyocytes and thereby titrates cellular translation in response to developmental and hypertrophic cues.

    The switch-like expression of heme-regulated kinase 1 mediates neuronal proteostasis following proteasome inhibition

    Beatriz Alvarez-Castelao et al.
    In neurons, inhibition of the proteasome results in feedback inhibition of protein synthesis, mediated by heme-regulated kinase 1, which is optimized to act as both a sensor and an effector.

    Dynamics of ribosomes and release factors during translation termination in E. coli

    Sarah Adio et al.
    Translation termination is a stochastic process that utilizes loosely coupled motions of its players to complete protein synthesis and release the newly synthesized nascent chain toward its cellular destination.

    CRISPR-mediated genetic interaction profiling identifies RNA binding proteins controlling metazoan fitness

    Adam D Norris et al.
    Synthetic genetic analysis in C. elegans identifies pairs of RNA binding protein genes that play a critical role in organism health and development.

    Cell-specific non-canonical amino acid labelling identifies changes in the de novo proteome during memory formation

    Harrison Tudor Evans et al.
    Quantitative de novo proteomics paired with in vivo cell-specific non-canonical amino acid labelling identified several spatial long-term memory-induced changes in protein synthesis in hippocampal neurons.

    Ubiquilin1 promotes antigen-receptor mediated proliferation by eliminating mislocalized mitochondrial proteins

    Alexandra M Whiteley et al.
    Stimulation of cells with a mitochondria-depolarizing mitogen reveals a requirement for UBQLN1 expression in maintaining protein synthesis levels during cell cycle entry.
