caspase-5 p10 CRISPR Activation Plasmid (h) | sc-401520-ACT | 20 µg | $397.00 |
Human CASP5 encodes caspase-5, an inflammatory caspase whose p10 small subunit is generated during proteolytic maturation of the zymogen and contributes to formation of the active protease complex. CASP5 participates in innate immune signaling downstream of cytosolic danger sensing, promoting inflammatory caspase activity that can drive pyroptotic cell death and cytokine processing, often in coordination with inflammasome pathways. Its expression and activation state are studied in contexts of infection, sterile inflammation, and myeloid cell activation, where dysregulated inflammatory caspase signaling can influence tissue injury phenotypes. CASP5 is therefore relevant to mechanisms linking pattern-recognition signaling, cell death programs, and inflammatory gene expression networks.
caspase-5 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CASP5 expression without altering the underlying DNA sequence.
caspase-5 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CASP5 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 CASP5 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous caspase-5 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CASP5 locus and enabling the study of caspase-5-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of caspase-5 pathway restoration in tumor cells with silenced or reduced CASP5 expression.
