In Xenopus, a cytoplasmic agent known as MPF induces entry into mitosis. In fission yeast, genetic studies have shown that the cdc2 kinase regulates mitotic initiation. The 13 kd product of the suc1 gene interacts with the cdc2 kinase in yeast cells. We show that the yeast suc1 gene product (p13) is a potent inhibitor of MPF in cell-free extracts from(More)
