ING4 CRISPR Activation Plasmid (h) | sc-403707-ACT | 20 µg | $397.00 |
ING4 (inhibitor of growth family member 4) encodes a nuclear tumor suppressor–like protein that functions as a chromatin-associated regulator of transcription. ING4 participates in histone acetylation–linked complexes and influences gene expression programs governing cell cycle control, apoptosis, DNA damage responses, and cellular senescence, with documented cross-talk to p53 and NF-κB signaling. By modulating inflammatory transcriptional outputs and stress-responsive pathways, ING4 helps constrain aberrant proliferation and regulates responses to genotoxic and oxidative stress. Altered ING4 expression or function has been associated with oncogenic phenotypes and dysregulated inflammatory signaling across multiple cancer-relevant contexts, making it a useful node for mechanistic studies of epigenetic control.
ING4 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ING4 expression without altering the underlying DNA sequence.
ING4 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ING4 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 ING4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ING4 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ING4 locus and enabling the study of ING4-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ING4 pathway restoration in tumor cells with silenced or reduced ING4 expression.
