    A mutation uncouples the tubulin conformational and GTPase cycles, revealing allosteric control of microtubule dynamics

    Elisabeth A Geyer, Alexander Burns ... Luke M Rice
    A buried mutation in αβ-tubulin reveals an allosteric response to GDP in the lattice that dictates microtubule catastrophe and shrinking.

    Ion channels and calcium signaling in motile cilia

    Julia F Doerner, Markus Delling, David E Clapham
    Direct patch clamp of ependymal motile cilia reveals that voltage-gated calcium channels in the cell body dominate their electrical and calcium signaling properties.

    Distinct mechanisms define murine B cell lineage immunoglobulin heavy chain (IgH) repertoires

    Yang Yang, Chunlin Wang ... Leonore A Herzenberg
    The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.

    Oligomerization of p62 allows for selection of ubiquitinated cargo and isolation membrane during selective autophagy

    Bettina Wurzer, Gabriele Zaffagnini ... Sascha Martens
    Oligomerization of p62/SQSTM1 generates high avidity binding regions that enable it to spatially select for concentrated ubiquitin and ATG8-family proteins.

    FAM150A and FAM150B are activating ligands for anaplastic lymphoma kinase

    Jikui Guan, Ganesh Umapathy ... Ruth H Palmer
    The secreted molecules FAM150A and FAM150B bind to the ALK RTK extracellular domain, potently activating the receptor activation and driving downstream signaling events.

    Salt-inducible kinases mediate nutrient-sensing to link dietary sugar and tumorigenesis in Drosophila

    Susumu Hirabayashi, Ross L Cagan
    The ability of tumors to respond to nutritional signals is mediated by Salt-inducible kinases, which ensure tumor growth under nutrient-rich conditions including obesity.
