- Enzyme Activity Assay (EAA)
- Characteristics
- The EZH2 protein complex, active contains EZH2, EED and Suz12 which are the minimal components required for histone methyltransferase activity. EZH2 is specific for H3 lysine 27, a mark of repressed regions of chromatin. Recombinant human EZH2 (accession number NM_004456, amino acids 2-end with an N-terminal His tag, molecular weight 86 kDa) was coexpressed in a baculovirus expression system along with human EED (accession number NM_003797, amino acids 2-end with an N-terminal FLAG tag, molecular weight 51 kDa) and human Suz12 (accession number NM_015355, amino acids 2-end with an N-terminal His tag, molecular weight 87 kDa).

- Application Notes
- Recombinant EZH2 protein complex is suitable for use in histone methyltransferase assays. This protein is useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Specific Activity: 0.08 pmol/min/μg. Assay conditions: Prepare a 50 μL reaction mix (20 mM phosphate pH 7.4, 0.05 % Tween-20, 40 μM S-adenosylmethionine, and 250-2000 ng enzyme complex) and add to substrate-coated wells with the substrate on a Thermo Neutravidin black plate. Incubate for 1 hr. Add anti-methyl histone H3K27 antibody and incubate 1hr. Next, incubate 1h with the HRP-labeled secondary antibody followed by chemiluminescent detection.

- Background
- EZH2, EED and Suz12 are present in the PRC protein complexes that function as mediators of epigenetic transcriptional silencing. EZH2 - (Enhancer of Zeste homolog 2, also designated Enx1 and SETDB1) is a human homolog of the Drosophila Enhancer of Zeste protein. It contains a SET domain that catalyzes the mono-, di- and trimethylation of Histone H3 Lys27. Polycomb group proteins repress gene expression by binding to chromatin and locally altering chromatin structure. Deregulation of EZH2 is linked to a variety of cancers.
