  • Patent number: 6017708
    Abstract: The cDNA of the human Myt1 kinase (Myt1Hu), which catalyzes phosphorylation of Cdc2 on Thr 14 and Tyr 15, has been cloned and sequenced. The invention provides isolated, purified and structurally defined DNA encoding Myt1Hu, isolated and purified Myt1Hu protein, a method for making Myt1Hu protein by expressing the DNA encoding Myt1Hu and methods for measuring levels of Myt1Hu in RNA or of Myt1Hu protein in a cell sample. Also provided are chimeric proteins having Cdc2 kinase activity.

  • Patent number: 5863729
    Abstract: Entry into mitosis requires the activity of the Cdc25C phosphatase which functions to activate Cdc2/Cyclin B. In asychronously growing cells, Cdc25C is stoichiometrically phosphorylated on serine 216. Levels of serine 216 phosphorylation remain constant throughout the G1-, S- and G2-phases of the cell cycle. A human kinase, denoted TcAK1 (for Twenty-five C Associated protein Kinase) that phosphorylates Cdc25C on serine 216 has been cloned and sequenced. A method is also provided for measuring levels of TcAK1 in RNA or of TcAK1 protein in cells. Phosphorylation of Cdc25C on serine 216 with TCAK1 creates a 14-3-3 recognition motif. The interaction between Cdc25C and 14-3-3 proceeds in a phosphorylation-specific manner. TcAK1 functions to mediate interaction between 14-3-3 proteins and other cellular proteins associated with oncogenesis or key signalling events.
