Abstract
Post-translational modification, including protein methylation, plays an important role in regulating protein function. The present invention provides a novel assay for evaluating demethylase activity and the discovery of a family of protein demethylases comprising a novel demethylase motif.

24. A method of identifying a compound that modulates the demethylase activity of a demethylase comprising a JmjC domain, the method comprising:
-
(a) contacting the demethylase with a methylated protein substrate in the presence of a test compound; and (b) detecting the level of demethylation of the protein substrate under conditions sufficient for demethylation, wherein a change in demethylation of the protein substrate as compared with the level of demethylation in the absence of the test compound indicates that the test compound is a modulator of the demethylase activity of the demethylase. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 35, 36, 39, 40, 43, 44, 47, 48, 49, 50, 64)

51. A method of identifying a candidate compound for treating cancer, the method comprising:
-
(a) contacting a histone demethylase comprising a JmjC domain with a methylated histone substrate in the presence of a test compound; and (b) detecting the level of demethylation of the histone substrate under conditions sufficient for demethylation, wherein a change in demethylation of the histone substrate as compared with the level of demethylation in the absence of the test compound indicates that the test compound is a candidate compound for the treatment of cancer. - View Dependent Claims (52, 53, 54, 56, 57, 58, 60, 61, 63, 96)
