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.

Application Notes

Recombinant EZH2 protein complex is suitable for use in histone methyltransferase assays.

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.
