    Rhodopsin targeted transcriptional silencing by DNA-binding

    Salvatore Botta, Elena Marrocco ... Enrico Maria Surace
    Photoreceptor genomic binding of a 20 base-pair-long DNA sequence by a synthetic DNA-binding protein turns off Rhodopsin expression.

    Subretinal mononuclear phagocytes induce cone segment loss via IL-1β

    Chiara M Eandi, Hugo Charles Messance ... Florian Sennlaub
    IL-1β release from macrophages might be responsible for the unexplained cone segment loss in retinal degenerative diseases that are associated with subretinal inflammation, such as retinitis pigmentosa or geographic atrophy.

    The ubiquitin-proteasome system regulates focal adhesions at the leading edge of migrating cells

    Anjali Teckchandani, Jonathan A Cooper
    A ubiquitin E3 ligase localizes to focal adhesions at the front of migrating human cells where it regulates cytoskeletal dynamics by targeting a focal adhesion protein.

    Eukaryotic translation initiation factor 3 plays distinct roles at the mRNA entry and exit channels of the ribosomal preinitiation complex

    Colin Echeverría Aitken, Petra Beznosková ... Jon R Lorsch
    Eukaryotic translation initiation factor 3 (eIF3) is required to stabilize the binding of mRNA at the exit channel of the small ribosomal subunit and acts at the entry channel to accelerate mRNA recruitment to the translation preinitiation complex.

    Chemotactic network responses to live bacteria show independence of phagocytosis from chemoreceptor sensing

    Netra Pal Meena, Alan R Kimmel
    Eukaryotic chemotaxis to live bacteria was quantified at a high throughput level, for the first time, and mechanistically examined for the interrelationship between chemotaxis and phagocytosis.

    A potent human neutralizing antibody Fc-dependently reduces established HBV infections

    Dan Li, Wenhui He ... Jianhua Sui
    A novel and potent receptor-binding-blockage human neutralizing antibody prevents HBV infection, and suppresses HBV infection therapeutically in HBV-infected mice.

    Identification of PNG kinase substrates uncovers interactions with the translational repressor TRAL in the oocyte-to-embryo transition

    Masatoshi Hara, Sebastian Lourido ... Terry L Orr-Weaver
    The threonine kinase controls maternal mRNA translation phosphorylate components of the translational machinery, including translational repressors, which appear to inactivate to promote the oocyte-to-embryo transition.

    The yeast H+-ATPase Pma1 promotes Rag/Gtr-dependent TORC1 activation in response to H+-coupled nutrient uptake

    Elie Saliba, Minoas Evangelinos ... Bruno André
    The H+ influx coupled to nutrient uptake and the plasma membrane H+-ATPase are central actors of the activation of target of rapamycin complex 1 (TORC1) in budding yeast Saccharomyces cerevisiae..

    DET1-mediated degradation of a SAGA-like deubiquitination module controls H2Bub homeostasis

    Amr Nassrallah, Martin Rougée ... Fredy Barneche
    Light signaling components interact with a histone H2B deubiquitination module, adjusting chromatin states at global level during Arabidopsis seedling development.

    The insulin/IGF signaling cascade modulates SUMOylation to regulate aging and proteostasis in Caenorhabditis elegans

    Lorna Moll, Noa Roitenberg ... Ehud Cohen
    By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.
