Protein phosphatase 2A (PP2A) promotes anaphase entry after DNA replication stress in budding yeast.
Title: Protein phosphatase 2A (PP2A) promotes anaphase entry after DNA replication stress in budding yeast.
Here, we show that Rts1 is required for the proportional relationship between cell size and growth rate during mitosis. Moreover, nutrients and Rts1 influence the duration and extent of growth in mitosis via Wee1 and Pds1/securin, two conserved regulators of mitotic progression.
Title: A Conserved PP2A Regulatory Subunit Enforces Proportional Relationships Between Cell Size and Growth Rate.
Swe1 and the Polo-like kinase Cdc5 control the balance between phosphorylated and unphosphorylated forms of Mih1, which is, in turn, important for mitotic spindle elongation.
Title: Swe1 and Mih1 regulate mitotic spindle dynamics in budding yeast via Bik1.
Moreover, the authors show that high levels of histones promote Swe1(WEE1) stabilisation thereby triggering the phosphorylation and inhibition of Cdc28(CDK1) through a mechanism different of the canonical DNA damage response.
Title: High levels of histones promote whole-genome-duplications and trigger a Swe1(WEE1)-dependent phosphorylation of Cdc28(CDK1).
strict temporal regulation of M-phase cyclin-dependent kinase (CDK; M-CDK) is important for polarity establishment and morphogenesis. Cells with premature M-CDK activity caused by loss of checkpoint kinase Swe1 failed to polarize and underwent anaphase without budding. Mutants with increased Swe1-dependent M-CDK inhibition showed additional or more penetrant phenotypes in RTG than mitosis
Title: Prolonged cyclin-dependent kinase inhibition results in septin perturbations during return to growth and mitosis.
Wee1 distinguishes spindle pole bodies to guide their pattern of age-dependent segregation.
Title: Budding yeast Wee1 distinguishes spindle pole bodies to guide their pattern of age-dependent segregation.
Swe1 kinase perceives alterations in sphingolipid (SL) homeostasis, activates SL synthesis, and may thus represent the missing regulatory link that controls the SL rheostat during the cell cycle
Title: Regulation of Sphingolipid Biosynthesis by the Morphogenesis Checkpoint Kinase Swe1.
propose a model by which TG-derived sphingolipids are required to activate the protein phosphatase 2A (PP2A(Cdc55)) to attenuate Swe1 phosphorylation
Title: Morphogenesis checkpoint kinase Swe1 is the executor of lipolysis-dependent cell-cycle progression.
Swe1 regulation by Cdc14 allows proper coordination of spindle elongation with mitotic progression.
Title: Budding yeast Swe1 is involved in the control of mitotic spindle elongation and is regulated by Cdc14 phosphatase during mitosis.
Transition from meiotic prophase to mitosis requires modulation of Cdk1 activity to coordinate cell-cycle events. Swe1 prevents formation of multinucleate cells by restraining M phase CDK activity to allow bud formation prior to nuclear division.
Title: Cdk1 modulation ensures the coordination of cell-cycle events during the switch from meiotic prophase to mitosis.
