Background: EZH2 is the catalytic subunit of the PRC2/EED-EZH2 complex, which methylates Lys9 (H3K9me) and Lys27 (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate Lys27 of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Compared to EZH2-containing complexes, it is more abundant in embryonic stem cells and plays a major role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1, CDKN2A and retinoic acid target genes. EZH2 can also methylate non-histone proteins such as the transcription factor GATA4.

Specific Activity: 0.08 pmole/min/µg Assay Conditions: 50 µl reaction mix (20 mM phosphate pH 7.4, 0.05% Tween-20, 40 µM S-adenosylmethionine, and 250-2000 ng enzyme complex) is added to the wells coated with histone H3 substrate on a Neutravidin black plate (ThermoFisher). Incubate for 1 hr. Add antibody against methylated K27 residue of histone H3, incubate 1 hr. Then, add secondary HRP-labeled antibody and incubate 30 min. Add HRP chemiluminescent substrates and read luminescence. Format: Aqueous buffer solution
