SUZ12 CRISPR Activation Plasmid (h) | sc-401551-ACT | 20 µg | $397.00 |
SUZ12 encodes a core component of Polycomb Repressive Complex 2 (PRC2), which cooperates with EZH2 and EED to establish and maintain repressive chromatin states through H3K27 methylation. By modulating chromatin accessibility, SUZ12 contributes to stable transcriptional silencing programs that regulate lineage specification, cell-cycle control, and developmental gene networks. Altered PRC2 activity involving SUZ12 has been linked to disrupted epigenetic regulation in multiple cancer contexts and neurodevelopmental phenotypes, making it a key node in studies of chromatin remodeling and transcriptional homeostasis. SUZ12-dependent repression intersects with pathways controlling differentiation, proliferation, and DNA damage responses via broad effects on gene expression.
SUZ12 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SUZ12 expression without altering the underlying DNA sequence.
SUZ12 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SUZ12 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 SUZ12 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous SUZ12 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SUZ12 locus and enabling the study of SUZ12-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of SUZ12 pathway restoration in tumor cells with silenced or reduced SUZ12 expression.
