OGG1 CRISPR Activation Plasmid (m) | sc-422012-ACT | 20 µg | $397.00 |
Mouse Ogg1 encodes 8-oxoguanine DNA glycosylase 1 (OGG1), a key enzyme in base excision repair that recognizes and excises oxidized purines such as 8-oxoG to prevent G:C to T:A transversions. By initiating repair at sites of oxidative DNA damage, OGG1 helps preserve genome stability in the context of mitochondrial and nuclear reactive oxygen species exposure. OGG1 activity intersects with oxidative stress responses, replication-associated repair processes, and mutagenesis control pathways that influence cellular aging and inflammatory signaling. Altered OGG1 function or regulation is frequently studied in models of cancer susceptibility, neurodegeneration, metabolic dysfunction, and other conditions linked to elevated oxidative damage burden.
OGG1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Ogg1 expression without altering the underlying DNA sequence.
OGG1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Ogg1 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 Ogg1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous OGG1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Ogg1 locus and enabling the study of OGG1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of OGG1 pathway restoration in tumor cells with silenced or reduced Ogg1 expression.
