    Nup98 FG domains from diverse species spontaneously phase-separate into particles with nuclear pore-like permselectivity

    Hermann Broder Schmidt, Dirk Görlich
    How nuclear pore complexes establish their permeability barrier has been a long-standing question; now, this process can be reconstituted by a surprisingly simple and rapid self-assembly of Nup98 FG domains into selective FG phases.

    Architecture of the ring formed by the tubulin homologue FtsZ in bacterial cell division

    Piotr Szwedziak, Qing Wang ... Jan Löwe
    The architecture of the bacterial cytokinetic ring in cells and in artificial liposome reconstitutions has been described using electron microscopy, leading to a mechanism of constriction.

    Enhanced homology-directed human genome engineering by controlled timing of CRISPR/Cas9 delivery

    Steven Lin, Brett T Staahl ... Jennifer A Doudna
    Building on previous work (Jinek et al., 2013), we report a simple and robust system to achieve high fidelity and high efficiency (30% of homologous recombination) genome engineering by homology-directed repair pathway in human cells using cell cycle synchronization and timed delivery of Cas9 ribonucleoprotein complexes.

    Proteomic analysis of the response to cell cycle arrests in human myeloid leukemia cells

    Tony Ly, Aki Endo, Angus I Lamond
    Building on previous work (Ly et al., 2014), we show that elutriated cells and arrested cells have similar patterns of DNA content and cyclin expression: however, a large fraction of the proteome changes detected in arrested cells are found to reflect arrest-specific responses rather than physiological cell cycle regulation.

    Specificity in endoplasmic reticulum-stress signaling in yeast entails a step-wise engagement of HAC1 mRNA to clusters of the stress sensor Ire1

    Eelco van Anken, David Pincus ... Peter Walter
    Selective docking of HAC1 mRNA on Ire1 clusters at a site separate from the Ire1 RNase domain is key for endoplasmic reticulum stress signaling.

    LINKIN, a new transmembrane protein necessary for cell adhesion

    Mihoko Kato, Tsui-Fen Chou ... Paul W Sternberg
    LINKIN and three of its interactors-RUVBL1, RUVBL2, and α-tubulin-are required for cells to migrate together during organogenesis.

    Early asymmetric cues triggering the dorsal/ventral gene regulatory network of the sea urchin embryo

    Vincenzo Cavalieri, Giovanni Spinelli
    During early embryogenesis of the sea urchin, asymmetrical positioning of the dorsal/ventral organizer relies upon the suppression of organizer activities in dorsal blastomeres by the Hbox12 homeodomain-containing repressor.

    An intracellular anion channel critical for pigmentation

    Nicholas W Bellono, Iliana E Escobar ... Elena Oancea
    Oculocutaneous albinism II (OCA2) contributes to a melanosome-specific anion channel that modulates organellar pH and is critical for melanin synthesis.

    Fast retrieval and autonomous regulation of single spontaneously recycling synaptic vesicles

    Jeremy Leitz, Ege T Kavalali
    Spontaneous fusion of vesicles at synapses is regulated independently of fusion triggered by action potentials, adding to evidence that the two types of fusion have distinct functions.

    Dynamic recruitment of the curvature-sensitive protein ArhGAP44 to nanoscale membrane deformations limits exploratory filopodia initiation in neurons

    Milos Galic, Feng-Chiao Tsai ... Tobias Meyer
    Local inward plasma membrane deformations caused by actomyosin-dependent contraction trigger the dynamic recruitment of a curvature-sensitive actin-regulatory protein, which represents a receptor-independent auto-regulatory mechanism to control local actin polymerization dynamics at the plasma membrane.
