    Fatty acid remodeling by LPCAT3 enriches arachidonate in phospholipid membranes and regulates triglyceride transport

    Tomomi Hashidate-Yoshida et al.
    LPCAT3 incorporates arachidonic acid into membrane phospholipids, which promotes lipoprotein assembly by enabling triacylgylcerols to cluster in the membrane.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

    Regulation of multispanning membrane protein topology via post-translational annealing

    Reid C Van Lehn et al.
    Coarse-grained modeling reveals a new mechanism for multispanning membrane protein topogenesis, in which misintegrated configurations of the proteins undergo post-translational annealing to reach final, fully integrated multispanning topologies.

    Boundary cells restrict dystroglycan trafficking to control basement membrane sliding during tissue remodeling

    Shelly TH McClatchey et al.
    A Notch-mediated signaling pathway upregulates a Sec14-GOLD phosphopholipid binding protein that promotes a morphogenetic process important in tissue remodeling and renewal.

    Unique membrane properties and enhanced signal processing in human neocortical neurons

    Guy Eyal et al.
    Models and experiments reveal that human L2/3 pyramidal neurons have distinctively low specific membrane capacitance which might have a significant impact on signal processing in human neocortex.

    Distinct structural and catalytic roles for Zap70 in formation of the immunological synapse in CTL

    Misty R Jenkins et al.
    Inhibition of the catalytic activity of the Zap70 kinase reveals that discrete TCR-regulated events control the remodelling of the actin cytoskeleton when the cytotoxic T cell interacts with its target.

    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.

    The coordinated action of the MVB pathway and autophagy ensures cell survival during starvation

    Martin Müller et al.
    A catabolic cascade is essential to enter a stable G1/G0 quiescent state and survive extended periods of starvation.
