    Hidden long-range memories of growth and cycle speed correlate cell cycles in lineage trees

    Erika E Kuchen et al.
    The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.

    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.

    The evolutionary plasticity of chromosome metabolism allows adaptation to constitutive DNA replication stress

    Marco Fumasoni, Andrew W Murray
    Evolutionary adaptation to a constitutive perturbation of DNA replication reveals that adaptive mutations in three conserved pathways interact to restore faithful chromosome replication and segregation.

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

    Margarida Moura et al.
    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 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.

    Eya2 promotes cell cycle progression by regulating DNA damage response during vertebrate limb regeneration

    Konstantinos Sousounis et al.
    Experimental manipulation of a core DNA damage response factor and cell-cycle checkpoint regulators reveals a key role for these processes in the progenitor cells that fuel limb regeneration.

    DNA damage checkpoint activation impairs chromatin homeostasis and promotes mitotic catastrophe during aging

    Matthew M Crane et al.
    Activation of a DNA-damage cell cycle checkpoint during aging causes genome instability and senescence in yeast mother cells.

    Cell Cycle: Micromanaging checkpoint proteins

    Andrea Ciliberto, Silke Hauf
    The kinase Mps1, long known to be the 'boss' in mitotic checkpoint signaling, phosphorylates multiple proteins in the checkpoint signaling cascade.
