    The Cas4-Cas1-Cas2 complex mediates precise prespacer processing during CRISPR adaptation

    Hayun Lee, Yukti Dhingra, Dipali G Sashital
    During CRISPR adaptation, Cas4 forms a ternary complex with the Cas1-Cas2 spacer integration complex, an interaction that coordinates substrate hand-off following precise, PAM-dependent prespacer processing prior to integration.

    Parallel CRISPR-Cas9 screens clarify impacts of p53 on screen performance

    Anne Ramsay Bowden, David A Morales-Juarez ... Stephen P Jackson
    The protein p53 negatively impacts the ability of a CRISPR screen to discriminate between essential and non-essential genes, hence, p53 status should be considered in these screens.

    Arrayed CRISPRi and quantitative imaging describe the morphotypic landscape of essential mycobacterial genes

    Timothy J de Wet, Kristy R Winkler ... Digby F Warner
    A high-throughput functional genomics approach combining inducible CRISPR-interference and quantitative imaging yields an atlas of 'phenoprints' to guide gene function assignments, identify metabolic pathway-specific morphotypes, and inform antibiotic mechanism-of-action studies.

    Transcription termination and antitermination of bacterial CRISPR arrays

    Anne M Stringer, Gabriele Baniulyte ... Joseph T Wade
    Many bacteria use the Nus factor antitermination complex to prevent premature Rho-dependent transcription termination of their CRISPR arrays.
