DJ-1 CRISPR Activation Plasmid (m) | sc-425380-ACT | 20 µg | $397.00 |
Mouse Park7 encodes DJ-1, a redox-responsive protein that supports cellular homeostasis under oxidative and mitochondrial stress. DJ-1 modulates antioxidant defenses, regulates proteostasis and autophagy-related processes, and influences transcriptional programs linked to metabolism and stress adaptation. In neurons and glia, DJ-1 intersects with pathways governing mitochondrial quality control and reactive oxygen species buffering, making Park7 a widely used locus for studying stress resilience mechanisms. Altered DJ-1 function is frequently investigated in models of neurodegeneration and inflammatory stress to understand how redox signaling impacts cell survival and vulnerability.
DJ-1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Park7 expression without altering the underlying DNA sequence.
DJ-1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Park7 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 Park7 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DJ-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Park7 locus and enabling the study of DJ-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DJ-1 pathway restoration in tumor cells with silenced or reduced Park7 expression.
