    Regulation of canonical Wnt signalling by the ciliopathy protein MKS1 and the E2 ubiquitin-conjugating enzyme UBE2E1

    Katarzyna Szymanska, Karsten Boldt ... Colin A Johnson
    Interacting MKS1 and UBE2E1 regulate canonical Wnt signaling through modulation of beta-catenin levels at the base of primary cilium, providing new insights into ciliopathy disease mechanisms.

    Protein Phosphatase 1 inactivates Mps1 to ensure efficient Spindle Assembly Checkpoint silencing

    Margarida Moura, Mariana Osswald ... Carlos Conde
    Inactivation of the master mitotic checkpoint regulator Mps1 by protein phosphatase 1 is required for timely segregation of the genetic material during cell division.

    A sequential multi-target Mps1 phosphorylation cascade promotes spindle checkpoint signaling

    Zhejian Ji, Haishan Gao ... Hongtao Yu
    The spindle checkpoint kinase Mps1 sequentially phosphorylates multiple substrates to amplify checkpoint signals, making the checkpoint highly dependent on Mps1 function and directly responsive to kinetochore-microtubule attachment.

    CXCR4high megakaryocytes regulate host-defense immunity against bacterial pathogens

    Jin Wang, Jiayi Xie ... Meng Zhao
    scRNA-seq identified CXCR4high MKs can funtionally regulate host-defense immune response against bacterial infection.

    A bend, flip and trap mechanism for transposon integration

    Elizabeth R Morris, Heather Grey ... Julia M Richardson
    Structural and biochemical analyses of a eukaryotic DNA transpososome in the integration step reveal how mariner/Tc1 transposons are selectively integrated into a TA target sequence.

    Deficit of mitogen-activated protein kinase phosphatase 1 (DUSP1) accelerates progressive hearing loss

    Adelaida M Celaya, Isabel Sánchez-Pérez ... Isabel Varela-Nieto
    Mitogen-activated protein kinase phosphatase 1 (DUSP1) deficiency causes early redox imbalance and increased inflammatory response in the cochlea, leading to cell loss and progressive neurosensory hearing loss.

    Identification of octopaminergic neurons that modulate sleep suppression by male sex drive

    Daniel R Machado, Dinis JS Afonso ... Kyunghee Koh
    The balance between sleep and sex drives determines whether male flies sleep or court, and a subset of octopaminergic neurons interact with the Fruitless-expressing courtship circuit to suppress sleep for sustained courtship.

    Rho-associated kinase (ROCK) function is essential for cell cycle progression, senescence and tumorigenesis

    Sandra Kümper, Faraz K Mardakheh ... Christopher J Marshall
    The Rho kinases ROCK1 and 2 act redundantly in regulating cell proliferation and their depletion causes cellular senescence.

    Cdc6 is sequentially regulated by PP2A-Cdc55, Cdc14, and Sic1 for origin licensing in S. cerevisiae

    Jasmin Philip, Mihkel Örd ... Amy E Ikui
    Pre-RC component Cdc6 is primed for origin licensing by phosphatases and Cdk1 inhibitor.

    Dzip1 and Fam92 form a ciliary transition zone complex with cell type specific roles in Drosophila

    Jean-André Lapart, Marco Gottardo ... Bénédicte Durand
    Genetic analyses in Drosophila establish the functional hierarchy of the ciliary transition zone module, Dzip1/Fam92/Cby, and reveal tissue specific variations in basal body anchoring pathways in fly ciliated tissues.
