    Matrin 3-dependent neurotoxicity is modified by nucleic acid binding and nucleocytoplasmic localization

    Ahmed M Malik et al.
    The deposition of Matrin 3, a DNA/RNA binding protein implicated in ALS and FTD, results in neurodegeneration dependent upon its localization, self-association, and ability to bind nucleic acids.

    Structural basis of nucleic-acid recognition and double-strand unwinding by the essential neuronal protein Pur-alpha

    Janine Weber et al.
    The crystal structure of Pur-alpha in complex with DNA reveals its molecular mechanisms of nucleic-acid binding and unwinding, allowing for a better understanding of its essential role in neurons.

    Impact of nucleic acid and methylated H3K9 binding activities of Suv39h1 on its heterochromatin assembly

    Atsuko Shirai et al.
    Suv39h1 chromodomain possesses nucleic acid-binding activity and this activity is coupled with its H3K9 methylation recognition in assembling heterochromatin.

    Structural insights into the nucleic acid remodeling mechanisms of the yeast THO-Sub2 complex

    Sandra K Schuller et al.
    The THO-Sub2 complex is an asymmetric homodimer that uses the spatial arrangement of two Sub2 helicases to prevent RNA:DNA hybrids.

    Viral genome structures are optimal for capsid assembly

    Jason D Perlmutter et al.
    Computer simulations reveal that viral nucleic acids have an ideal structure for being packaged into outer protein shells called capsids.

    Tight nuclear tethering of cGAS is essential for preventing autoreactivity

    Hannah E Volkman et al.
    Tight nuclear tethering of the cGAS DNA sensor maintains it in its resting state and prevents activation by self-DNA.

    Random-sequence genetic oligomer pools display an innate potential for ligation and recombination

    Hannes Mutschler et al.
    Random sequence RNA pools display an innate capacity for ligation and recombination, enabling them to “bootstrap” themselves towards higher compositional, informational and structural complexity.

    Molecular insights into RNA and DNA helicase evolution from the determinants of specificity for a DEAD-box RNA helicase

    Anna L Mallam et al.
    The core domains of an RNA helicase interact with a wide variety of NTPs and nucleic acids suggesting how related enzymes may have evolved to have diverse functions.

    Bacterial fumarase and L-malic acid are evolutionary ancient components of the DNA damage response

    Esti Singer et al.
    The dual function of an ancient prokaryotic enzyme, which is linked to specific metabolite signals, may have been the evolutionary driving force behind its dual localization in eukaryotes.

    Nucleophosmin integrates within the nucleolus via multi-modal interactions with proteins displaying R-rich linear motifs and rRNA

    Diana M Mitrea et al.
    Nucleolar protein localization involves the phase separation within the nucleolar matrix via three types of multivalent features: acidic tracts, nucleic acid binding domains and arginine-rich low complexity sequences.
