    Bub3 reads phosphorylated MELT repeats to promote spindle assembly checkpoint signaling

    Ivana Primorac et al.
    The spindle assembly protein Bub3 recruits the checkpoint kinase Bub1 to kinetochores by binding to phosphorylated MELT repeats in the kinetochore subunit Knl1.

    BUB-1 targets PP2A:B56 to regulate chromosome congression during meiosis I in C. elegans oocytes

    Laura Bel Borja et al.
    BUB-1 recruits PP2A/B56 to regulate chromosome congression in meiosis I.

    Probing the catalytic functions of Bub1 kinase using the small molecule inhibitors BAY-320 and BAY-524

    Anna P Baron et al.
    Chemical inhibition of Bub1 shows that the catalytic activity is not required for normal mitotic progression, but it makes chromosome segregation and cell proliferation more sensitive to the effects of the anti-cancer drug Paclitaxel.

    A molecular basis for the differential roles of Bub1 and BubR1 in the spindle assembly checkpoint

    Katharina Overlack et al.
    The mechanism behind the recruitment of the spindle assembly checkpoint protein BubR1 to the kinetochore illustrates how gene duplication and sub-functionalization can influence the functional complexity of a protein network.

    The copy-number and varied strengths of MELT motifs in Spc105 balance the strength and responsiveness of the spindle assembly checkpoint

    Babhrubahan Roy et al.
    Cell biological and genetic analyses reveal how budding yeast cells optimize Spindle Assembly checkpoint signaling to maximize chromosome segregation accuracy and minimize unnecessary delays in anaphase onset.

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

    Zhejian Ji et al.
    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.
