    The tardigrade damage suppressor protein binds to nucleosomes and protects DNA from hydroxyl radicals

    Carolina Chavez, Grisel Cruz-Becerra ... James T Kadonaga
    Dsup, a unique protein found only in tardigrades, is a nucleosome-binding protein that protects DNA from damage by hydroxyl radicals, such as those generated by ionizing radiation or oxidants.

    A genetic selection reveals functional metastable structures embedded in a toxin-encoding mRNA

    Sara Masachis, Nicolas J Tourasse ... Fabien Darfeuille
    A genetic selection of toxicity suppressors coupled to high-throughput sequencing has captured metastable RNA structures that co-transcriptionally inhibit the translation of a bacterial toxin.

    A nuclear role for the DEAD-box protein Dbp5 in tRNA export

    Azra Lari, Arvind Arul Nambi Rajan ... Ben Montpetit
    Within the nucleus, Dbp5p supports tRNA export providing a parallel mechanism by which this conserved DEAD-box protein functions to support eukaryotic gene expression.

    A conserved Mcm4 motif is required for Mcm2-7 double-hexamer formation and origin DNA unwinding

    Kanokwan Champasa, Caitlin Blank ... Stephen P Bell
    Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.

    TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

    Rosa María Marión, Juan J Montero ... Maria A Blasco
    Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.

    piRNA-guided co-transcriptional silencing coopts nuclear export factors

    Martin H Fabry, Filippo Ciabrelli ... Benjamin Czech
    A member of the Drosophila Nuclear Export Factor (Nxf) family, Nxf2, forms part of the piRNA-dependent co-transcriptional silencing complex and is essential for transposon repression in fly ovaries.

    PUMILIO, but not RBMX, binding is required for regulation of genomic stability by noncoding RNA NORAD

    Mahmoud M Elguindy, Florian Kopp ... Joshua T Mendell
    Interaction with PUMILIO is essential for maintenance of genomic stability by the cytoplasmic long noncoding RNA NORAD, whereas binding to RBMX is dispensable for this function.

    Epimutations are associated with CHROMOMETHYLASE 3-induced de novo DNA methylation

    Jered M Wendte, Yinwen Zhang ... Robert J Schmitz
    Simultaneous targeting of loci by pathways that promote euchromatin and heterochromatin primes transcribed genes for epimutations in the form of CG DNA methylation.

    Acetylation of BMAL1 by TIP60 controls BRD4-P-TEFb recruitment to circadian promoters

    Nikolai Petkau, Harun Budak ... Gregor Eichele
    Acetylation of the circadian transcription factor BMAL1 by the acetyltransferase TIP60 is crucial for recruitment of the pause release factors to clock gene promoters and productive elongation of these genes.
