    Knockout of Slo2.2 enhances itch, abolishes KNa current, and increases action potential firing frequency in DRG neurons

    Pedro L Martinez-Espinosa et al.
    Sodium-activated potassium ion currents encoded by the kcnt1 gene delay action potential firing in DRG neurons by activity preceding an action potential.

    Free-energy simulations reveal molecular mechanism for functional switch of a DNA helicase

    Wen Ma et al.
    Integration of structural bioinformatics and free-energy simulations reveals how a helicase switches its function from unwinding to rezipping DNA, during which a key metastable conformation is predicted and verified by single-molecule measurements.

    LAST, a c-Myc-inducible long noncoding RNA, cooperates with CNBP to promote CCND1 mRNA stability in human cells

    Limian Cao et al.
    A c-Myc-transcribed long noncoding RNA namely LAST (LncRNA-assisted stabilization of transcripts) collaborates with a cellular factor CNBP to promote the stability of CCND1/cyclin D1 mRNA post-transcriptionally, ensuring the proper G1/Sphase transition of the cell cycle.

    Action of CMG with strand-specific DNA blocks supports an internal unwinding mode for the eukaryotic replicative helicase

    Lance Langston, Mike O’Donnell
    The CMG complex, the replicative helicase in eukaryotes, uses a different mechanism from bacterial and viral helicases by engaging both strands of parental DNA with substantial force and unwinding the duplex within the central channel of CMG.

    Tet2 and Tet3 cooperate with B-lineage transcription factors to regulate DNA modification and chromatin accessibility

    Chan-Wang Lio et al.
    TET methylcytosine oxidases cooperate with B lineage-specific transcription factors to promote immunoglobulin gene rearrangement by depositing 5hmC, facilitating DNA demethylation and increasing chromatin accessibility at enhancers.

    Viral RNA switch mediates the dynamic control of flavivirus replicase recruitment by genome cyclization

    Zhong-Yu Liu et al.
    A conserved element in the flavivirus genomic 5′ terminus switches its conformation in response to long-range RNA interactions, and thereby regulates the dynamic recruitment of viral replicase for efficient viral RNA replication.

    cryo-EM structures of the E. coli replicative DNA polymerase reveal its dynamic interactions with the DNA sliding clamp, exonuclease and τ

    Rafael Fernandez-Leiro et al.
    Structures of the replicative DNA polymerase Pol IIIα, the DNA sliding clamp, the proofreading exonuclease, and the processivity switch Tau (τ) suggest a mechanism for quick release during lagging strand synthesis.

    Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint

    Nicolas Bigot et al.
    Two phosphorylation sites on 53BP1 are found to mediate interaction with TOPBP1-RAD9 and shown to be essential for assembling the G1 DNA damage checkpoint response apparatus.

    IFI16, a nuclear innate immune DNA sensor, mediates epigenetic silencing of herpesvirus genomes by its association with H3K9 methyltransferases SUV39H1 and GLP

    Arunava Roy et al.
    The innate immune DNA sensor IFI16 is in association with H3K9 methyltransferases SUV39H1 and GLP under physiological conditions in the nucleus which facilitates the epigenetic silencing of foreign viral DNA.

    Highly efficient 5' capping of mitochondrial RNA with NAD+ and NADH by yeast and human mitochondrial RNA polymerase

    Jeremy G Bird et al.
    Eukaryotic mitochondrial RNA polymerases cap RNA with NAD with much higher efficiencies than nuclear RNA polymerase II; as a consequence, mitochondrial RNAs have remarkably high levels of NAD capping.
