    Re-examining how complexin inhibits neurotransmitter release

    Thorsten Trimbuch et al.
    Challenging a widespread model, biophysical and electrophysiological experiments suggest a new mechanism whereby complexins inhibit neurotransmitter release through electrostatic repulsion between their accessory helix and the membranes.

    Phosphorylation-mediated PTEN conformational closure and deactivation revealed with protein semisynthesis

    David Bolduc et al.
    C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.

    Control of the polyamine biosynthesis pathway by G2-quadruplexes

    Helen Louise Lightfoot et al.
    An ensemble of conserved G2-quadruplex structures in the untranslated regions of messenger RNAs from genes in the polyamine bioysynthesis pathway sense polyamine levels and regulate polyamine synthesis in cells.

    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li et al.
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

    Daniel Šmít et al.
    Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.

    Neto auxiliary proteins control both the trafficking and biophysical properties of the kainate receptor GluK1

    Nengyin Sheng et al.
    Auxiliary subunits Neto1 and Neto2 regulate the GluK1 receptor targeting to excitatory silent synapses through different molecular mechanisms and also modify receptor biophysics through distinct mechanisms.

    Cell-wall remodeling drives engulfment during Bacillus subtilis sporulation

    Nikola Ojkic et al.
    Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.
