    CRISPRi is not strand-specific at all loci and redefines the transcriptional landscape

    Françoise S Howe et al.
    CRISPR interference (CRISPRi), which uses small guide RNAs to target catalytically dead Cas9 protein to chromatin, disrupts existing transcription units and generates new sites for initiation and termination of transcription on both strands of DNA.

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman et al.
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.

    Nerve growth factor receptor negates the tumor suppressor p53 as a feedback regulator

    Xiang Zhou et al.
    The nerve growth factor receptor (NGFR) protein regulates p53 via two negative feedback mechanisms, which are hijacked by cancer cells.

    SETD2 is required for DNA double-strand break repair and activation of the p53-mediated checkpoint

    Sílvia Carvalho et al.
    The involvement of SETD2 in an important DNA repair pathway could explain the high frequency of SETD2 mutations in several cancers and may provide an alternative mechanism to evade the p53-mediated checkpoint.

    Small molecule-mediated refolding and activation of myosin motor function

    Michael B Radke et al.
    The small molecule EMD 57033 is one of a new class of pharmacological chaperones that stabilize, enhance the activity of, and correct stress-induced misfolding of myosin proteins.

    Dynamic regulation of transcription factors by nucleosome remodeling

    Ming Li et al.
    Single molecule DNA unzipping reveals a novel model for the regulation of transcription factors and nucleosome positioning via nucleosome remodeling in yeast.

    MicroRNA-mediated repression of nonsense mRNAs

    Ya Zhao et al.
    microRNAs can serve as a surveillance system to repress nonsense mRNAs by recognizing miRNA-responsive elements in the open reading frame region downstream of the premature termination codon.

    The dyskerin ribonucleoprotein complex as an OCT4/SOX2 coactivator in embryonic stem cells

    Yick W Fong et al.
    A previously unrecognized transcriptional coactivator function of the dyskerin ribonucleoprotein complex and its associated small nucleolar RNA has been uncovered and mediates embryonic stem cell-specific transcription.

    Small molecule inhibition of apicomplexan FtsH1 disrupts plastid biogenesis in human pathogens

    Katherine Amberg-Johnson et al.
    An unbiased chemical screen identifies the AAA+ membrane metalloprotease FtsH1 as a novel apicoplast biogenesis factor and druggable antimalarial target.

    Tau and spectraplakins promote synapse formation and maintenance through Jun kinase and neuronal trafficking

    Andre Voelzmann et al.
    A novel regulatory cascade downstream of Tau and spectraplakins ensures that synaptic proteins are delivered to axonal terminals in the developing and ageing brain, providing potential explanations for precocious synapse loss in dementias.
