Mouse Ezh2 encodes the histone lysine methyltransferase ENX-1, the catalytic subunit of Polycomb repressive complex 2 (PRC2) that deposits H3K27me3 to maintain transcriptional silencing programs. ENX-1 regulates chromatin compaction, lineage specification, cell-cycle progression, and repression of developmental regulators, integrating with epigenetic control of enhancers and promoters across differentiation states. Dysregulated EZH2/PRC2 activity is widely studied in cancer biology, stem cell maintenance, and immune cell differentiation, where altered H3K27 methylation can rewire gene expression networks. Ezh2 is therefore a central node for investigating chromatin-mediated control of proliferation, fate commitment, and transcriptional plasticity in mouse models.
ENX-1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Ezh2 expression without altering the underlying DNA sequence.
ENX-1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Ezh2 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the Ezh2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ENX-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Ezh2 locus and enabling the study of ENX-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ENX-1 pathway restoration in tumor cells with silenced or reduced Ezh2 expression.
