ZNF804A CRISPR Activation Plasmid (h) | sc-403525-ACT | 20 µg | $397.00 |
ZNF804A encodes a zinc finger–containing protein implicated in transcriptional regulation and neurodevelopmental gene expression programs. In human cells, ZNF804A has been linked to processes including neuronal differentiation, synaptic connectivity, and activity-dependent signaling that shape cortical circuitry. Genetic and expression studies associate ZNF804A variation with susceptibility to neuropsychiatric phenotypes, supporting its use as a molecular entry point for investigating risk-associated regulatory networks. Experimentally, modulation of ZNF804A helps map downstream transcriptional changes and pathway interactions relevant to brain development and neuronal function.
ZNF804A CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ZNF804A expression without altering the underlying DNA sequence.
ZNF804A CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ZNF804A 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 ZNF804A transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ZNF804A expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ZNF804A locus and enabling the study of ZNF804A-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ZNF804A pathway restoration in tumor cells with silenced or reduced ZNF804A expression.
