    Molecular determinants in Frizzled, Reck, and Wnt7a for ligand-specific signaling in neurovascular development

    Chris Cho et al.
    Molecular dissection of Frizzled, Reck, and Wnt7a provides critical insight into the long-standing question of ligand-receptor specificity in the field of Wnt signaling.

    NirD curtails the stringent response by inhibiting RelA activity in Escherichia coli

    Loïc Léger et al.
    Genetic and biochemical approaches uncover a novel mode of regulation of the alarmone synthetase RelA through a functional and direct interaction with the small subunit of the nitrite reductase NirD.

    Lis1 regulates dynein by sterically blocking its mechanochemical cycle

    Katerina Toropova et al.
    Structural and functional studies reveal how a ubiquitous regulator of dynein keeps the microtubule-based motor in a persistent track-bound state.

    Palaeogenomes of Eurasian straight-tusked elephants challenge the current view of elephant evolution

    Matthias Meyer et al.
    DNA sequences from the Middle Pleistocene reveal that the extinct Eurasian straight-tusked elephants were closely related to today's African forest elephants (Loxodonta cyclotis) in Africa.

    Septal secretion of protein A in Staphylococcus aureus requires SecA and lipoteichoic acid synthesis

    Wenqi Yu et al.
    Surface protein precursors traffic to lipoteichoic acid-rich septal membranes of Staphylococcus aureus for cleavage of their YSIRK-GXXS motif signal peptides and SecA-mediated translocation across the plasma membrane.

    Single-molecule observation of ATP-independent SSB displacement by RecO in Deinococcus radiodurans

    Jihee Hwang et al.
    RecO efficiently displaces SSB from ssDNA without consuming ATPs using its two DNA-binding sites, even though SSB binds to ssDNA approximately 300 times more strongly than RecO does.

    Recombinational branch migration by the RadA/Sms paralog of RecA in Escherichia coli

    Deani L Cooper, Susan T Lovett
    The role of the bacterial protein RadA in homologous recombination – a DNA repair pathway vital to all cells – is defined.

    RecA filament sliding on DNA facilitates homology search

    Kaushik Ragunathan et al.
    A DNA–protein complex can find target sequences of bases in another DNA molecule by sliding along it.

    Real-time experimental control using network-based parallel processing

    Byounghoon Kim et al.
    The Real-Time Experimental Control with Graphical User Interface (REC-GUI) framework can facilitate cutting-edge neuroscience research by providing precise experimental control using high-level programming environments familiar to many experimentalists.

    The human cytoplasmic dynein interactome reveals novel activators of motility

    William B Redwine et al.
    Using a proximity-dependent labeling approach in living cells, the human cytoplasmic dynein-1 interactome was identified and a new family of dynein activators, ninein and ninein-like, was discovered.
