    Selective dephosphorylation by PP2A-B55 directs the meiosis I-meiosis II transition in oocytes

    S Zachary Swartz, Hieu T Nguyen ... Arminja N Kettenbach
    Time-course phosphoproteomics reveals that selective dephosphorylation is critical for directing the MI/MII transition and that, through its inherent phospho-threonine preference, PP2A-B55 imposes specific phosphoregulated behaviors that distinguish the two meiotic divisions.

    An in vitro stem cell model of human epiblast and yolk sac interaction

    Kirsty ML Mackinlay, Bailey AT Weatherbee ... Magdalena Zernicka-Goetz
    Human yolk sac-like cells, which share characteristics with the post-implantation human hypoblast, can model the interaction between the epiblast and hypoblast that occurs during early human development.

    CTP and parS coordinate ParB partition complex dynamics and ParA-ATPase activation for ParABS-mediated DNA partitioning

    James A Taylor, Yeonee Seol ... Kiyoshi Mizuuchi
    CTP and centromere-like parS-DNA act synergistically and catalytically to activate ParB, which remains activated after leaving parS to tune ParA–ParB and ParB–ParB interaction dynamics for robust ParABS-mediated F-plasmid DNA segregation.

    Processing of the ribosomal ubiquitin-like fusion protein FUBI-eS30/FAU is required for 40S maturation and depends on USP36

    Jasmin van den Heuvel, Caroline Ashiono ... Ulrike Kutay
    Endoproteolytic cleavage of the ribosomal precursor protein FUBI-eS30 is required for efficient maturation of small ribosomal subunits in the cytoplasm of human cells and involves the nucleolar deubiquitinase USP36.

    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.

    Twisting of the zebrafish heart tube during cardiac looping is a tbx5-dependent and tissue-intrinsic process

    Federico Tessadori, Erika Tsingos ... Jeroen Bakkers
    The three-dimensional and asymmetrical transformations undergone by the zebrafish linear heart tube during looping morphogenesis are under the control of cardiac-intrinsic cues.
