Il15ra encodes the mouse interleukin-15 receptor alpha chain (IL-15Rα), a high-affinity binding component that presents IL-15 in trans to IL-2/15Rβ–γc complexes on neighboring immune cells. This axis is central to NK cell development and survival, memory CD8+ T cell homeostasis, and shaping innate and adaptive immune responses through JAK/STAT signaling. IL-15Rα-dependent signaling influences lymphocyte trafficking and activation programs, making Il15ra regulation relevant to studies of inflammation, immune-mediated pathology, and tumor immunology. Altered IL-15/IL-15Rα activity has been linked to dysregulated cytokine networks and aberrant immune cell expansion in diverse disease models.
IL-15Rα CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Il15ra expression without altering the underlying DNA sequence.
IL-15Rα CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Il15ra 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 Il15ra transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous IL-15Rα expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Il15ra locus and enabling the study of IL-15Rα-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of IL-15Rα pathway restoration in tumor cells with silenced or reduced Il15ra expression.
