    Characterization of human translesion DNA synthesis across a UV-induced DNA lesion

    Mark Hedglin et al.
    Quantitative binding and kinetic assays on DNA polymerases η and δ define the mechanism for polymerase exchange during human translesion DNA synthesis across a UV-induced lesion on the lagging strand.

    A nascent polypeptide sequence modulates DnaA translation elongation in response to nutrient availability

    Michele Felletti et al.
    Specific amino acids in the N-terminus of the replication initiator protein DnaA inhibit translation elongation upon carbon starvation, illustrating that the identity of the N-terminal amino acids of a protein can modulate protein synthesis yield under changing conditions.

    Determination of host proteins composing the microenvironment of coronavirus replicase complexes by proximity-labeling

    Philip V'kovski et al.
    The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.

    Role of the visual experience-dependent nascent proteome in neuronal plasticity

    Han-Hsuan Liu et al.
    A screen of visual-experience induced changes in newly-synthesized proteins in Xenopus optic tectum identifies unexpected candidate plasticity proteins.

    Vasohibin1, a new mouse cardiomyocyte IRES trans-acting factor that regulates translation in early hypoxia

    Fransky Hantelys et al.
    In mouse cardiomyocytes, (lymph)angiogenic growth factors are induced during early hypoxia by a translational mechanism involving a new IRES trans-acting factor, vasohibin-1.

    Coordination between nucleotide excision repair and specialized polymerase DnaE2 action enables DNA damage survival in non-replicating bacteria

    Asha Mary Joseph et al.
    Live-cell imaging shows that replication-independent specialized polymerase action is a consequence of lesion processing via NER and impacts cellular survival under stress outside replicative phases of the cell cycle.

    Arabidopsis RCD1 coordinates chloroplast and mitochondrial functions through interaction with ANAC transcription factors

    Alexey Shapiguzov et al.
    Signalling and metabolic interactions of the plant energy organelles, chloroplasts and mitochondria, depend on the nuclear regulatory protein RCD1.

    The translation elongation factor eEF1A1 couples transcription to translation during heat shock response

    Maria Vera et al.
    Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.
