Encompassing Amino Acids: 2-end
Applications: Useful for Western blot analysis and to investigate protein-protein interactions in the EZH2 complex.
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: Human EZH2 (GenBank Accession No. NM_004456), a.a. 2-end with N-terminal His-GST-tag, MW= 114 kDa, expressed in a Sf9 baculovirus expression system. This protein is inactive alone, although it is functional if combined with other proteins in the complex.
