    A mitotic kinase scaffold depleted in testicular seminomas impacts spindle orientation in germ line stem cells

    Heidi Hehnly, David Canton ... John D Scott
    A protein kinase complex that is important for cell division is lost in testicular seminoma, which is a common cancer in men.

    Assembly and positioning of actomyosin rings by contractility and planar cell polarity

    Ivonne M Sehring, Pierre Recho ... Di Jiang
    Contractility wins over the polarity pathway in a tug-of-war to position a cytokinesis-like actomyosin ring at the equator of notochord cells.

    Matrix metalloproteinase 14 is required for fibrous tissue expansion

    Susan H Taylor, Ching-Yan Chloé Yeung ... Karl E Kadler
    The membrane type I-matrix metalloproteinase is essential for the release of collagen fibrils from plasma membrane fibripositors, which is required for the transition from embryonic to postnatal tendon development.

    Paradoxical resistance of multiple myeloma to proteasome inhibitors by decreased levels of 19S proteasomal subunits

    Diego Acosta-Alvear, Min Y Cho ... Martin Kampmann
    The nodes of the cytosolic proteostasis network can control sensitivity to proteasome inhibitors and decreased levels of the 19S proteasomal regulator can lead to increased resistance to inhibitors.

    NOCA-1 functions with γ-tubulin and in parallel to Patronin to assemble non-centrosomal microtubule arrays in C. elegans

    Shaohe Wang, Di Wu ... Karen Oegema
    The C. elegans ninein homolog NOCA-1 is important for the assembly of non-centrosomal microtubule arrays required for embryo production, nuclear positioning and larval development.

    In vivo dynamics of skeletal muscle Dystrophin in zebrafish embryos revealed by improved FRAP analysis

    Fernanda Bajanca, Vinicio Gonzalez-Perez ... Simon M Hughes
    A multidisciplinary approach was used to translate the mathematical analysis of Dystrophin movements inside muscle cells into the biology of how Dystrophin interacts with the cell membrane.

    The GARP complex is required for cellular sphingolipid homeostasis

    Florian Fröhlich, Constance Petit ... Tobias C Walther
    The retrograde vesicular trafficking GARP complex, which is mutated in a neurodegenerative disease, is important for sphingolipid homeostasis in yeast and mammalian cells.

    Roles of the membrane-reentrant β-hairpin-like loop of RseP protease in selective substrate cleavage

    Koichiro Akiyama, Shinya Mizuno ... Yoshinori Akiyama
    Mutational analysis and biochemical experiments suggest that the conserved β-hairpin-like membrane-reentrant loop of RseP - an S2P family intramembrane cleaving protease - helps to discriminate substrates by directly interacting with their transmembrane segments.

    KPNB1 mediates PER/CRY nuclear translocation and circadian clock function

    Yool Lee, A Reum Jang ... John B Hogenesch
    KPNB1 regulates rhythmic spatio-temporal nuclear import of the PER/CRY complex and is required for negative feedback repression in mammalian and fly clock function.
