    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani et al.
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    General decapping activators target different subsets of inefficiently translated mRNAs

    Feng He et al.
    Dhh1, Pat1, and Lsm1 target subsets of cellular mRNAs for decapping via interactions of these regulatory proteins with the C-terminal domain of Dcp2, the catalytic component of the decapping enzyme.

    Engineering a conserved RNA regulatory protein repurposes its biological function in vivo

    Vandita D Bhat et al.
    Motif length plays a critical role in the specification of biological function within a conserved family of RNA-binding proteins.

    The proteasome biogenesis regulator Rpn4 cooperates with the unfolded protein response to promote ER stress resistance

    Rolf M Schmidt et al.
    Endoplasmic reticulum stress in yeast activates not only the UPR but also Rpn4, promoting the clearance of misfolded proteins from the cytosol as part of a modular cross-compartment stress response.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Gene activation by a CRISPR-assisted trans enhancer

    Xinhui Xu et al.
    Both exogenous and endogenous genes can be highly activated in cells by a new dCas9-based activator, CRISPR-assisted trans enhancer, that can be used to activate genes for biomedical applications.

    Condensin controls cellular RNA levels through the accurate segregation of chromosomes instead of directly regulating transcription

    Clémence Hocquet et al.
    Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.

    aPKC-mediated displacement and actomyosin-mediated retention polarize Miranda in Drosophila neuroblasts

    Matthew Robert Hannaford et al.
    The actomyosin network and phospho-regulation combine to polarize fate determinants at the Drosophila neuroblast cell cortex.

    Exon junction complex proteins bind nascent transcripts independently of pre-mRNA splicing in Drosophila melanogaster

    Subhendu Roy Choudhury et al.
    Deposition of the exon junction complex is thought to be the missing link between pre-mRNA splicing and translation in multicellular organisms, but no evidence of such deposition has been found in Drosophila.

    Dissecting the pre-placodal transcriptome to reveal presumptive direct targets of Six1 and Eya1 in cranial placodes

    Nick Riddiford, Gerhard Schlosser
    RNA sequencing of the African clawed frog has identified hundreds of putative direct Six1 and Eya1 target genes, including transcriptional regulators of neuronal progenitors and neuronal/sensory differentiation.
