    Cryo-EM structure of the bifunctional secretin complex of Thermus thermophilus

    Edoardo D'Imprima et al.
    The pilus extrusion/DNA uptake system of Thermus thermophilus contains a 13-mer of the 757-residue PilQ protein and a tightly bound protein outside the outer membrane with a role in DNA binding.

    A mitochondria-anchored isoform of the actin-nucleating spire protein regulates mitochondrial division

    Uri Manor et al.
    An actin nucleating protein, Spire1C, localizes to the mitochondrial outer membrane and interacts with the endoplasmic reticulum-anchored formin protein INF2 to drive mitochondrial fission.

    A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro

    Tobias Brandt et al.
    A combination of an in vitro mitochondrial fusion assay with electron cryo-tomography (cryo-ET) reveals distinct steps and protein complexes during mitofusin-dependent fusion between adjacent mitochondrial outer membranes.

    Caveolae internalization repairs wounded cells and muscle fibers

    Matthias Corrotte et al.
    Cells repair damage to their outer membranes not by patching them as previously thought, but by using proteins called caveolins to remove the damaged regions by endocytosis.
