CDK1-Cyclin B mediated phosphorylation of PP2A-B56 on B56Par1.T73T75 controls mitotic entry timing and Schizosaccharomyces pombe cell size

Abstract Mitosis is triggered when the rising activity of CDK1-Cyclin B, amplified by the CDK1/Cdc25/Wee1 feedback loop, overcomes inhibitory signalling from Wee1 and counteracting phosphatases. CDK-opposing phosphatases PP1, PP2A-B55 and PP2A-B56 are regulators of mitosis. A scr...
