Scientific Background: EZH2 (enhancer of zeste homolog 2) belongs to the polycomb group (PcG) protein and acts as the catalytic subunit of the PRC2/EED-EZH2 complex, which methylates 'Lys-27' of histone H3, leading to transcriptional repression of target genes. EZH2 expression is associated with proliferating tissues and shares an overlapping set of target genes with EZH1. Compared to PRC2-EZH1, PRC2-EZH2 exhibits higher levels of histone methyltransferase (HKMT) activity.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the Polycomb-group (PcG) family. PcG family members form multimeric protein complexes, which are involved in maintaining the transcriptional repressive state of genes over successive cell generations. This protein associates with the embryonic ectoderm development protein, the VAV1 oncoprotein, and the X-linked nuclear protein. This protein may play a role in the hematopoietic and central nervous systems. Multiple alternatively splcied transcript variants encoding distinct isoforms have been identified for this gene.

Uniprot Description
EZH2: a histone H3 Lys 27 (H3K27) methyltransferase and Polycomb group protein with oncogenic activity. A master regulatory protein that plays a critical role in development. Catalytic subunit of the PRC2/EED-EZH2 complex, which methylates K9 and K27 of histone H3, leading to transcriptional repression of the affected target genes. PRC2 includes the Ezh2, EED, SUZ12, RBBP4 and RBBP7 and possibly AEBP2. The recruitment of PRC2 to a promoter leads to increased levels of di- and trimethylation of H3K27 (H3K27me2/3), regulating the balance between self-renewal and differentiation of embryonic stem cells (ESCs). The recruitment of PRC2 to promoters in ES cells is interdependent on Jarid 2. ESCs lacking the PRC2 component EED are deficient in Jarid2 promoter activity, while the knockdown of Jarid 2 reduces PRC2 at its target promoters. Able to mono-, di- and trimethylate K27 of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1, p14ARF and retinoic acid target genes. Binds ATRX via the SET domain. The PRC2 complex may also interact with DNMT1, DNMT3A, DNMT3B and PHF1 via the EZH2 subunit and with SIRT1 via the SUZ12 subunit. Interacts with HDAC1 and HDAC2. Interacts with PRAME. Overexpressed in numerous tumor types including carcinomas of the breast, colon, larynx, lymphoma and testis. Expression decreases during senescence of embryonic fibroblasts. Expression peaks at the G1/S phase boundary. Expression is induced by E2F1, E2F2 and E2F3. Expression is reduced in cells subject to numerous types of stress including UV-, IR- and bleomycin-induced DNA damage and by activation of p53. It has been reported that phosphorylation by AKT1 on S21 reduces methyltransferase activity.

Product Notes
The EZH2 ezh2 (Catalog #AAA515499) is a Recombinant Protein produced from Sf9 insect cells using baculovirus and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Full-length. AAA Biotech's EZH2 can be used in a range of immunoassay formats including, but not limited to, Methyltransferase Assay. Researchers should empirically determine the suitability of the EZH2 ezh2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "EZH2, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
