    The endonuclease Cue2 cleaves mRNAs at stalled ribosomes during No Go Decay

    Karole N D'Orazio et al.
    Cue2 is an endonuclease that cleaves mRNA in the A site of the lagging ribosome upon ribosome collision events.

    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.

    The yeast mating-type switching endonuclease HO is a domesticated member of an unorthodox homing genetic element family

    Aisling Y Coughlan et al.
    A family of homing genetic elements that look like inteins but work differently is the progenitor of the endonuclease that enables Saccharomyces cerevisiae to change its mating type.

    Biosynthesis of histone messenger RNA employs a specific 3' end endonuclease

    Ilaria Pettinati et al.
    MBLAC1 is an endoribonuclease specific for replication dependent histone pre-mRNA processing during S-phase and may represent a new type of cancer target.

    Single-molecule FRET unveils induced-fit mechanism for substrate selectivity in flap endonuclease 1

    Fahad Rashid et al.
    Structure specific nucleases that act in DNA replication, repair and recombination actively mold their DNA while transforming their own structure to achieve precise cleavage of their cognate DNA and avoid the deleterious cleavage of noncognate DNA.

    Essential roles of Caspase-3 in facilitating Myc-induced genetic instability and carcinogenesis

    Ian M Cartwright et al.
    Myc expression is shown to cause sublethal activation of Caspase-3 and downstream endonuclease G, which causes DNA double strand breaks and oncogenic transformation in human cells.

    A conserved RNA degradation complex required for spreading and epigenetic inheritance of heterochromatin

    Gergana Shipkovenska et al.
    Genetic and biochemical studies show that a conserved ribosome biogenesis complex also localizes to heterochromatin, where it triggers RNA degradation and promotes the spreading and epigenetic inheritance of histone methylation.

    A non-canonical role for the EDC4 decapping factor in regulating MARF1-mediated mRNA decay

    William R Brothers et al.
    Crosslink immunopreciptiation (iCLIP) studies reveal important mechanistic insights into how MARF1 post-transcriptionally regulates targeted mRNAs and uncover a novel mode by which EDC4 regulates mRNA metabolism.

    Local chromosome context is a major determinant of crossover pathway biochemistry during budding yeast meiosis

    Darpan Medhi et al.
    Different homologous recombination pathways are dominant in different regions of meiotic chromosomes, indicating that chromosome structure influences recombination biochemistry.

    Inhibiting IRE1α-endonuclease activity decreases tumor burden in a mouse model for hepatocellular carcinoma

    Nataša Pavlović et al.
    Inhibiting IRE1α decreases tumor cell proliferation and migration in hepatocellular carcinoma, therefore components of this ER-stress pathway may be therapeutically relevant for liver cancer.
