    DNA methylation presents distinct binding sites for human transcription factors

    Shaohui Hu et al.
    A comprehensive study of human transcription factors reveals that a greater number of these proteins bind to methylated DNA sequences than previously thought.

    Topoisomerase VI senses and exploits both DNA crossings and bends to facilitate strand passage

    Timothy J Wendorff, James M Berger
    The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.

    Dissection of specific binding of HIV-1 Gag to the 'packaging signal' in viral RNA

    Mauricio Comas-Garcia et al.
    While HIV-1 Gag protein binds tightly to several RNAs, it binds to the viral RNA 'packaging signal' with higher specificity than to control RNAs.

    A network of epigenetic modifiers and DNA repair genes controls tissue-specific copy number alteration preference

    Dina Cramer et al.
    The genetic background of a cancer cell and the chromatin organization of the tissue-of-origin impact the amount, length and position of somatic copy number alterations in cancer.

    In vivo reconstitution finds multivalent RNA–RNA interactions as drivers of mesh-like condensates

    Weirui Ma et al.
    Binding of a multivalent RNA-binding protein to mRNAs that are able to form pervasive RNA–RNA interactions induces formation of mesh-like condensates, whereas binding of mostly structured mRNAs induces sphere-like condensates.

    Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

    Yuling Li et al.
    Animal RanBP1 nuclear export and cargo dissociation mechanisms are surprisingly different from yeast, due to mutations of critical residues, leading to greater nuclear transport efficiency and higher energy cost.

    Community effects in regulation of translation

    Paul M Macdonald et al.
    Regulatory elements in an mRNA that act in cis to influence translation can also exert their effects in trans, in a process dependent on assembly of the mRNAs into particles.

    The near-atomic cryoEM structure of a flexible filamentous plant virus shows homology of its coat protein with nucleoproteins of animal viruses

    Xabier Agirrezabala et al.
    The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

    HspB8 prevents aberrant phase transitions of FUS by chaperoning its folded RNA-binding domain

    Edgar E Boczek et al.
    Quantitative time-resolved crosslinking mass spectrometry is developed to monitor protein interactions and dynamics inside molecular condensates and used to identify misfolding of the RNA-binding domain of FUS as a key driver of condensate-aging.

    Translation repression via modulation of the cytoplasmic poly(A)-binding protein in the inflammatory response

    Xu Zhang et al.
    The RNA-binding protein, Zfp36, which is critical for resolving inflammation, inhibits the production of proinflammatory cytokines via modulation of the cytoplasmic poly(A)-binding protein.
