Abstract excerpt
Cdc25 phosphatase primes entry to mitosis by removing the inhibitory phosphate that is transferred to mitosis promoting factor (MPF) by Wee1 related kinases. A positive feedback loop then boosts Cdc25 and represses Wee1 activities to drive full-scale MPF activation and commitment to mitosis. Dominant mutations in the Schizosaccharomyces pombe spindle pole body (SPB) component Cut12 enable cdc25.22 mutants to...
