RIP CRISPR Activation Plasmid (m) | sc-422681-ACT | 20 µg | $397.00 |
Ripk1 encodes receptor-interacting serine/threonine-protein kinase 1 (RIPK1/RIP), a key regulator of cell fate decisions downstream of TNF receptor, TLR, and cytosolic innate immune signaling. RIPK1 integrates pro-survival NF-κB signaling with apoptotic and necroptotic pathways through interactions with RIPK3, MLKL, and caspase-8, coordinating inflammatory outputs and stress responses. In mouse models, altered RIPK1 activity is linked to dysregulated cytokine signaling, tissue injury, and neuroinflammatory phenotypes, making it a widely used node for studying inflammation-associated pathology and regulated cell death.
RIP CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Ripk1 expression without altering the underlying DNA sequence.
RIP CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Ripk1 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 Ripk1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous RIP expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Ripk1 locus and enabling the study of RIP-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of RIP pathway restoration in tumor cells with silenced or reduced Ripk1 expression.
