    SKAP2 is required for defense against K. pneumoniae infection and neutrophil respiratory burst

    Giang T Nguyen, Lamyaa Shaban ... Joan Mecsas
    SKAP2 is critical for hematopoietic cell protection against Klebsiella infection in mouse lungs, for full phosphorylation of Src Family Kinases, Syk, and Pyk2, and for Klebsiella-induced reactive oxygen species production.

    Astrin-SKAP complex reconstitution reveals its kinetochore interaction with microtubule-bound Ndc80

    David M Kern, Julie K Monda ... Iain M Cheeseman
    Biochemical and cell biological analyses reveal that the Astrin-SKAP complex acts to stabilize kinetochore-microtubule interactions through its intrinsic microtubule binding activity and its association with the Ndc80 complex, the core component of the kinetochore-microtubule interface.

    The equatorial position of the metaphase plate ensures symmetric cell divisions

    Chia Huei Tan, Ivana Gasic ... Patrick Meraldi
    Human cells center the position of the metaphase plate before anaphase onset to ensure the formation of equal-sized daughter cells.

    Cyclin F drives proliferation through SCF-dependent degradation of the retinoblastoma-like tumor suppressor p130/RBL2

    Taylor P Enrico, Wayne Stallaert ... Michael J Emanuele
    The SCF-family of ubiquitin ligases regulates the key cancer proliferation node by controlling the degradation of RB-like tumor suppressor RBL2/p130.

    α-/γ-Taxilin are required for centriolar subdistal appendage assembly and microtubule organization

    Dandan Ma, Fulin Wang ... Jianguo Chen
    Super-resolution microscopy, biochemical and functional analyses reveal how α-taxilin and γ-taxilin are assembled at the subdistal appendages and their roles in microtubule organization.

    Kinetochores attached to microtubule-ends are stabilised by Astrin bound PP1 to ensure proper chromosome segregation

    Duccio Conti, Parveen Gul ... Viji M Draviam
    Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.

    Coordinated regulation of gene expression in Plasmodium female gametocytes by two transcription factors

    Yuho Murata, Tsubasa Nishi ... Masao Yuda
    Sequential expression of two transcription factors that bind to five- and ten-base female-specific cis-acting elements, respectively, promotes differentiation of Plasmodium female gametocytes.

    Chromatin-prebound Crm1 recruits Nup98-HoxA9 fusion to induce aberrant expression of Hox cluster genes

    Masahiro Oka, Sonoko Mura ... Yoshihiro Yoneda
    Nup98-HoxA9 is recruited to Hox gene cluster regions together with the chromosomally pre-bound nuclear export factor Crm1, which induces aberrant expression of several Hox genes and affecting the differentiation of embryonic stem cells.
