    PPP1R35 is a novel centrosomal protein that regulates centriole length in concert with the microcephaly protein RTTN

    Andrew Michael Sydor, Etienne Coyaud ... Vito Mennella
    The previously uncharacterized protein PPP1R35 is a novel centriolar luminal protein critical for centriole elongation by acting in a complex with microcephaly protein RTTN.

    Microcephaly-associated protein WDR62 shuttles from the Golgi apparatus to the spindle poles in human neural progenitors

    Claudia Dell'Amico, Marilyn M Angulo Salavarria ... Marco Onorati
    Microcephaly-associated mutations disrupt microtubule-dependent WDR62 translocation from the Golgi complex to the mitotic spindle poles, impair mitotic progression, and alter neurogenic trajectories in patient induced Pluripotent Stem Cell-derived 2D and 3D models of human neurodevelopment.

    Loss of ninein interferes with osteoclast formation and causes premature ossification

    Thierry Gilbert, Camille Gorlt ... Andreas Merdes
    It is shown that the absence of the centrosome protein ninein provokes premature ossification during mouse development, due to a defect in the fusion of precursor cells into syncytial osteoclasts.

    QIL1 mutation causes MICOS disassembly and early onset fatal mitochondrial encephalopathy with liver disease

    Virginia Guarani, Claude Jardel ... Manuel Schiff
    Building on previous work (Guarani et al., 2015), MICOS (mitochondrial contact site) assembly and cristae junction formation are shown to have a critical role in human health.

    Pathway-specific effects of ADSL deficiency on neurodevelopment

    Ilaria Dutto, Julian Gerhards ... Travis H Stracker
    Analysis of adenylosuccinate lyase (ADSL) deficiency in multiple experimental systems reveals cell and organismal phenotypes and impaired neurodevelopment due to the attenuation of ADSL's roles in distinct pathways.

    KDM5A mutations identified in autism spectrum disorder using forward genetics

    Lauretta El Hayek, Islam Oguz Tuncay ... Maria H Chahrour
    Successful autism spectrum disorder gene discovery using forward genetics identifies KDM5A, which encodes a histone H3 lysine 4 demethylase, as a disease gene.

    Tight junction protein occludin regulates progenitor Self-Renewal and survival in developing cortex

    Raphael M Bendriem, Shawn Singh ... M Elizabeth Ross
    That early cortical neural progenitor divisions strictly require OCLN isoform expression is a paradigm shift in the functional consideration of this protein best known for promoting between-cell barrier functions.

    Crystal structures of the CPAP/STIL complex reveal its role in centriole assembly and human microcephaly

    Matthew A Cottee, Nadine Muschalik ... Mark van Breugel
    Structural analyses of the centriole proteins CPAP and STIL identify domains that are critical for centriole formation and provide a structural explanation for a mutation that causes human microcephaly.

    Allelic strengths of encephalopathy-associated UBA5 variants correlate between in vivo and in vitro assays

    Xueyang Pan, Albert N Alvarez ... Hugo J Bellen
    A comprehensive platform is established for the evaluation of both current and future individuals afflicted with the UBA5-associated developmental and epileptic encephalopathy.

    Pericentrin-mediated SAS-6 recruitment promotes centriole assembly

    Daisuke Ito, Sihem Zitouni ... Mónica Bettencourt-Dias
    Newly discovered interaction between fission yeast SPB and animal centriole components reveals that pericentrin not only functions as a microtubule-nucleator, but also promotes centriole assembly in animals.
