    KAT2-mediated acetylation switches the mode of PALB2 chromatin association to safeguard genome integrity

    Marjorie Fournier, Amélie Rodrigue ... Fumiko Esashi
    The lysine acetyltransferases KAT2A and KAT2B regulate the dynamic chromatin association of the tumour suppressor protein PALB2, protecting active genes and promoting DNA damage repair in a context-dependent manner.

    Lack of CCDC146, a ubiquitous centriole and microtubule-associated protein, leads to non-syndromic male infertility in human and mouse

    Jana Muroňová, Zine Eddine Kherraf ... Christophe Arnoult
    CCDC146 is a structural component of the flagellum in sperm, located in the doublet microtubules of the axoneme, whose absence leads to multiple morphological anomalies of the flagellum.

    Mapping endothelial-cell diversity in cerebral cavernous malformations at single-cell resolution

    Fabrizio Orsenigo, Lei Liu Conze ... Elisabetta Dejana
    Single-cell RNA analysis of brain endothelium identifies the angiogenic venous capillary subset and respective resident endothelial progenitors at the origin of CCM lesions, while arterial endothelial cells are unaffected.

    Transcriptional immune suppression and up-regulation of double-stranded DNA damage and repair repertoires in ecDNA-containing tumors

    Miin S Lin, Se-Young Jo ... Vineet Bafna
    Extrachromosomal DNA containing tumors up-regulate DNA damage and repair, cell cycle control, and mitotic processes, but down-regulate global immune regulation pathways, suggesting new avenues for therapeutic intervention.

    A comparative study of the cryo-EM structures of Saccharomyces cerevisiae and human anaphase-promoting complex/cyclosome (APC/C)

    Ester Vazquez-Fernandez, Jing Yang ... David Barford
    The yeast APC/C cryo-EM structure reveals substantial similarities with the human APC/C structure but also important differences in mechanisms of phosphorylation-dependent regulation and activation by coactivators.

    Ordered dephosphorylation initiated by the selective proteolysis of cyclin B drives mitotic exit

    James Holder, Shabaz Mohammed, Francis A Barr
    Selective APC/C-mediated proteolysis of cyclin B drives progression through the metaphase-anaphase transition whilst wide-spread waves of dephosphorylation co-ordinate the subsequent events of mitotic exit.

    The transcription factors TFE3 and TFEB amplify p53 dependent transcriptional programs in response to DNA damage

    Owen A Brady, Eutteum Jeong ... Rosa Puertollano
    Disruption of TFEB and TFE3 results in diminished p53 signaling capacity and altered cell cycle regulation under genotoxic stress conditions.

    Stepwise assembly of the human replicative polymerase holoenzyme

    Mark Hedglin, Senthil K Perumal ... Stephen Benkovic
    Fluorescence resonance energy transfer has been used to explore the interactions between DNA polymerases, sliding clamps and clamp loaders as DNA is replicated in human cells.

    Polo-like kinase 1 induces epithelial-to-mesenchymal transition and promotes epithelial cell motility by activating CRAF/ERK signaling

    Jianguo Wu, Andrei I Ivanov ... Zheng Fu
    Overexpression of PLK1 triggers oncogenic transformation and transcriptional reprogramming of prostate epithelial cells, which stimulates cell migration and invasion.

    Novel mechanistic insights into the role of Mer2 as the keystone of meiotic DNA break formation

    Dorota Rousová, Vaishnavi Nivsarkar ... John R Weir
    Mer2 interacts directly with meiotic chromatin, axial proteins, and the DNA break forming machinery to facilitate the formation of meiotic double-strand breaks.
