IL-22Rα1 CRISPR Activation Plasmid (h) | sc-404104-ACT | 20 µg | $397.00 |
Human IL22RA1 encodes IL-22 receptor subunit alpha 1 (IL-22Rα1), a type II cytokine receptor chain that pairs with IL10RB to form the functional IL-22 receptor complex on epithelial and tissue barrier cells. Ligand engagement activates JAK/STAT signaling, with prominent STAT3 phosphorylation, and intersects with MAPK and PI3K/AKT pathways to regulate antimicrobial programs, mucosal restitution, and inflammatory gene expression. IL-22Rα1-mediated signaling is linked to barrier integrity in skin, lung, and gastrointestinal tissues and is frequently studied in contexts of chronic inflammation and epithelial dysregulation. Altered IL22RA1 expression or pathway activity has been associated with inflammatory disorders and epithelial tumor biology, making it a useful node for mechanistic studies of cytokine-driven tissue responses.
IL-22Rα1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous IL22RA1 expression without altering the underlying DNA sequence.
IL-22Rα1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the IL22RA1 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 IL22RA1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous IL-22Rα1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native IL22RA1 locus and enabling the study of IL-22Rα1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of IL-22Rα1 pathway restoration in tumor cells with silenced or reduced IL22RA1 expression.
