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.
Description: The EZH2 (A677G) Chemiluminescent Assay Kit is designed to measureactivity of the mutant EZH2 complex [EZH2 (A677G)/EED/SUZ12/RbAp48/AEBP] for screeningand profiling purposes. The key to the EZH2 (A677G) Assay Kit is a highly specific antibody that recognizes methylatedHistone H3K27. With this kit, only three simple steps on a microtiter plate are required formethyltransferase detection. First, S-adenosylmethionine is incubated with a sample containingassay buffer and methyltransferase enzyme for one hour. Next, primary antibody is added.Finally, the strips are treated with an HRP-labeled secondary antibody followed by addition ofthe HRP substrate to produce chemiluminescence that can then be measured using achemiluminescence reader.
Storage Stability: One year from date of receipt when stored as directed.
Supplied As: The EZH2 (A677G) Chemiluminescent Assay Kit comes in a convenient format, with wells precoated with histone H3 peptide substrate, an antibody against methylated K27 residue of Histone H3, the secondary HRP-labeled antibody, S-adenosylmethionine, methyltra
Warnings: Avoid freeze/thaw cycles.
