The present invention provides a general method for identify agents that modulate the activity of histone modifying enzymes, such as an acetylase, deacetylase, methyltransferase, demethylase, kinase, etc. The assay the of invention employs reconstituted, immobilized nucleosomes and fluorescence-based assays, such as fluorescence-based immunoassays, scintillation proximity assays, or FRET assays to determine whether the agent modulates the activity of the histone modifying enzymes. |
