    RNA-dependent chromatin association of transcription elongation factors and Pol II CTD kinases

    Sofia Battaglia, Michael Lidschreiber ... Patrick Cramer
    In vivo and in vitro elongation factor-RNA interaction data provide a missing link in understanding how processive elongation complexes are formed on active genes and disassembled at the end of genes.

    Emergence and propagation of epistasis in metabolic networks

    Sergey Kryazhimskiy
    Mutations that affect a metabolic network generically exhibit epistasis, which propagates to higher level phenotypes, such as fitness, carrying some information about the network’s topology.

    Cell-intrinsic and -extrinsic mechanisms promote cell-type-specific cytokinetic diversity

    Tim Davies, Han X Kim ... Julie C Canman
    Functional molecular analysis of cytokinesis in Caenorhabditis elegans four-cell embryos reveals cell-type-specific variation in the fundamental dependence on a robust f-actin cytoskeleton for successful cell division, mediated by both cell-intrinsic and -extrinsic pathways.

    Dynein-mediated transport and membrane trafficking control PAR3 polarised distribution

    Julie Jouette, Antoine Guichet, Sandra B Claret
    In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.

    HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase

    Johannes Rudolph, Genevieve Roberts ... Karolin Luger
    The polymerase activity of PARP1 is converted to hydrolase activity upon binding of Histone Parylation Factor 1 (HPF1) with nucleosome activators.

    Robust T cell activation requires an eIF3-driven burst in T cell receptor translation

    Dasmanthie De Silva, Lucas Ferguson ... Jamie HD Cate
    Binding of the translation initiation factor eIF3 to the messenger RNAs encoding the T cell receptor subunits alpha and beta is required to drive a short burst in their translation and promote a strong T cell response.

    N6-methyladenosine of HIV-1 RNA regulates viral infection and HIV-1 Gag protein expression

    Nagaraja Tirumuru, Boxuan Simen Zhao ... Li Wu
    Human proteins that add or remove the methyladenosine modification of cellular RNA, or recognize methylated RNA significantly affect HIV-1 infection or viral protein synthesis in cells, suggesting an important role for HIV-1 RNA methylation in regulating viral replication.

    Dual histone methyl reader ZCWPW1 facilitates repair of meiotic double strand breaks in male mice

    Mohamed Mahgoub, Jacob Paiano ... Todd S Macfarlan
    The meiotic recombination landscape in vertebrates was re-engineered via the co-evolution of a dual histone H3K4/H3K36 methylation 'writer' PRDM9 and its 'reader' ZCWPW1 that facilitates efficient double strand break repair.

    Aurora A and cortical flows promote polarization and cytokinesis by inducing asymmetric ECT-2 accumulation

    Katrina M Longhini, Michael Glotzer
    Centrosomal Aurora A (AIR-1), together with cortical actomyosin flows, induces polarization of ECT-2, the activator of RHO-1, during polarization and cytokinesis, in order to promote furrow formation.

    Repression of ferritin light chain translation by human eIF3

    Mia C Pulos-Holmes, Daniel N Srole ... Jamie H Cate
    Human ferritin light chain (FTL) mRNA translation is regulated via its 5'-untranslated region (5'-UTR) by three mechanisms: RNA folding, iron response protein binding, and eukaryotic translation initiation factor eIF3 binding.
