Fission yeast cells carrying a CDK1 mutation in which the tyrosine-15 residue is replaced by phenylalanine

show the same premature mitotic CDK activation and entry into mitosis.

Until Mitotic CDKs is not active, the activatory protein phosphatase, Cdc25, is phosphorylated, bound and inhibited by phosphoserine/threonine-binding protein 14-3-3.

#Section 3: Genetics, Cellular and Molecular Biology

The entire process of mitotic CDKs activation and entry into mitosis involves two positive feedback loops and coordination between events at the centrosome, in the cytoplasm, and in the nucleus.
