    Switch-like Arp2/3 activation upon WASP and WIP recruitment to an apparent threshold level by multivalent linker proteins in vivo

    Yidi Sun et al.
    Intersectin counterparts in yeast recruit WASP and WIP to endocytic sites to establish a robust multivalent SH3 domain-PRM interaction network which gives actin assembly onset a switch-like behavior in vivo.

    Single-molecule turnover dynamics of actin and membrane coat proteins in clathrin-mediated endocytosis

    Michael M Lacy et al.
    The main proteins of clathrin-mediated endocytosis bind and unbind rapidly, continuously turning over about five times during the formation of an endocytic vesicle in yeast.

    An ESCRT-LEM protein surveillance system is poised to directly monitor the nuclear envelope and nuclear transport system

    David J Thaller et al.
    ESCRT-driven mechanisms that sense and seal holes in the nuclear membranes directly monitor the nuclear transport system and the exposure of the inner nuclear membrane.

    Microtubule plus-ends act as physical signaling hubs to activate RhoA during cytokinesis

    Vikash Verma, Thomas J Maresca
    MT plus-end-mediated recruitment of a cortical pool of ECT2 trigger RhoA activation upon contact, which results in localized contractility during cytokinesis.

    Direct comparison of clathrin-mediated endocytosis in budding and fission yeast reveals conserved and evolvable features

    Yidi Sun et al.
    Quantitative comparison of clathrin-mediated endocytosis in budding and fission yeast identified conserved mechanisms and species-specific adaptations with broad implications that extend from yeast to humans.

    CYK-4 functions independently of its centralspindlin partner ZEN-4 to cellularize oocytes in germline syncytia

    Kian-Yong Lee et al.
    The CYK-4 subunit of the broadly conserved intercellular bridge component centralspindlin, but not its ZEN-4 subunit, is essential for the cytokinesis-like closure of intercellular bridges that cellularizes oocytes to separate them from germline syncytia.

    The role of scaffold reshaping and disassembly in dynamin driven membrane fission

    Martina Pannuzzo et al.
    Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.

    Timing of ESCRT-III protein recruitment and membrane scission during HIV-1 assembly

    Daniel S Johnson et al.
    During viral assembly, ESCRTIII and VPS4 are recruited after most of the HIV-1 membrane is bent but disappear prior to scission of the virion from the cell.

    TORC2-Gad8-dependent myosin phosphorylation modulates regulation by calcium

    Karen Baker et al.
    IQ domain phosphorylation regulates calmodulin binding and myosin-1 function.

    Evolutionarily unique mechanistic framework of clathrin-mediated endocytosis in plants

    Madhumitha Narasimhan et al.
    The examination of the ultra-structure and in vivo dynamics of endocytosis in plants reveal plants unique actin-independent, clathrin-mediated endocytosis mechanisms to overcome their unique physiological properties.
