  • Publication number: 20040029204
    Abstract: The invention concerns a method for obtaining human cdc 25B1, cdc25B2, cdcB3 and cdc25C phosphatases. More particularly, the invention concerns a protein for fusion between human cdc25B1, cdc25B2, cdcB3 or cdc25C phosphatase and the maltose binding protein (MBP) of Escherichia coli, the DNA sequence coding for said fusion protein, a method for preparing said fusion protein and a method for identifying human cdc25B1, cdc25B2, cdcB3 or cdc25C protein modulators.
