    The translational landscape of the splicing factor SRSF1 and its role in mitosis

    Magdalena M Maslon, Sara R Heras ... Javier F Cáceres
    Identifying the translational targets of the shuttling protein, SRSF1, reveals that it is needed for normal cell division, and suggests that it couples pre-mRNA splicing and translation.

    Chromosome mis-segregation and cytokinesis failure in trisomic human cells

    Joshua M Nicholson, Joana C Macedo ... Daniela Cimini
    Aneuploidy can cause chromosome mis-segregation and specific cellular phenotypes driven by expression of genes on the extra chromosome.

    Centriolar satellites assemble centrosomal microcephaly proteins to recruit CDK2 and promote centriole duplication

    Andrew Kodani, Timothy W Yu ... Jeremy F Reiter
    To control centriole duplication, centriolar satellite proteins assemble a microcephaly-associated protein complex at the centrosome and activate cyclin-dependent kinase 2.

    Tethering of an E3 ligase by PCM1 regulates the abundance of centrosomal KIAA0586/Talpid3 and promotes ciliogenesis

    Lei Wang, Kwanwoo Lee ... Brian D Dynlacht
    Ciliogenesis is regulated by a certain group of centriolar satellite proteins, among which an E3 ligase is tethered by PCM1 to maintain the normal level of pro-ciliogenic protein on centrioles.

    An extensive program of periodic alternative splicing linked to cell cycle progression

    Daniel Dominguez, Yi-Hsuan Tsai ... Zefeng Wang
    Extensive periodic regulation of alternative splicing during the cell cycle in genes is linked to cell cycle functions, and involves an auto-inhibitory mechanism that uses the protein kinase CLK1.

    TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin

    Fernando R Balestra, Andrés Domínguez-Calvo ... Pierre Gönczy
    TRIM37 prevents the formation of centriolar protein assemblies through an atypical de novo assembly pathway that would otherwise threaten genome integrity.

    CEP78 functions downstream of CEP350 to control biogenesis of primary cilia by negatively regulating CP110 levels

    André Brás Gonçalves, Sarah Kirstine Hasselbalch ... Lotte Bang Pedersen
    Analysis of mutant cells combined with biochemical experiments reveals that CEP78 is recruited to the centrosome by CEP350 and regulates ciliogenesis and ciliary length control through CP110-dependent and CP110-independent mechanisms, respectively.

    5-Hydroxymethylcytosine-mediated active demethylation is required for mammalian neuronal differentiation and function

    Elitsa Stoyanova, Michael Riad ... Nathaniel Heintz
    5-Hydroxymethylcytosine-mediated active DNA demethylation occurs in postmitotic neurons, and is required for their terminal differentiation and function.

    Zinc finger protein Zfp335 controls early T-cell development and survival through β-selection-dependent and -independent mechanisms

    Xin Wang, Anjun Jiao ... Baojun Zhang
    Genetically modified mouse model and comprehensive analysis reveal the molecular mechanisms regulating early T-cell development through intracellular TCRβ expression-mediated β-selection and independent cell survival signaling.
