    Synaptotagmin 1 directs repetitive release by coupling vesicle exocytosis to the Rab3 cycle

    Yunsheng Cheng et al.
    Experiments in C. elegans reveal how synaptotagmin and Rab3, the 'yin and yang' of synapses, control whether transmitter vesicles remain docked at the presynaptic membrane or release their contents into the synapse.

    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.

    Cytoplasmic dynein crosslinks and slides anti-parallel microtubules using its two motor domains

    Marvin E Tanenbaum et al.
    The motor domains of dynein are sufficient to crosslink microtubules and slide them antiparallel to each other.

    Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

    Mirko Messa et al.
    Epsin has a key role in the coupling of actin to endocytic clathrin coated pits that is required for their maturation and helps capture SNAREs at endocytic clathrin coated pits.

    Regulated aggregative multicellularity in a close unicellular relative of metazoa

    Arnau Sebé-Pedrós et al.
    The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.

    Therapeutic genetic variation revealed in diverse Hsp104 homologs

    Zachary M March et al.
    Exploring natural Hsp104 variation reveals unexpected tuning of a passive activity that inhibits aggregation of specific substrates to selectively counter TDP-43 or alpha-synuclein proteotoxicity connected to neurodegenerative disease.

    Heterogeneous T cell motility behaviors emerge from a coupling between speed and turning in vivo

    Elizabeth R Jerison, Stephen R Quake
    Motile interstitial T cells in live zebrafish access a broad range of length-scales due to long-lived cell-intrinsic variation in speed, and a coupling between speed and directional persistence.

    Genetic transformation of Spizellomyces punctatus, a resource for studying chytrid biology and evolutionary cell biology

    Edgar M Medina et al.
    Spizellomycespunctatusis a genetically tractable chytrid and model organism for comparative cell biology for understanding evolution of the cell cycle, actin dynamics, and cellularization in fungi and early eukaryotes.

    Plasticity of cell migration resulting from mechanochemical coupling

    Yuansheng Cao et al.
    Computational and experimental studies show that different migration modes of eukaryotic cells are the result of the interplay between signaling waves and cell mechanics.

    Mechanistic insights into the active site and allosteric communication pathways in human nonmuscle myosin-2C

    Krishna Chinthalapudi et al.
    R788 is part of an allosteric communication pathway that connects the converter at the distal end of the myosin motor domain via the relay helix with switch-2 of the active site.
