Calpain 5 CRISPR Activation Plasmid (h) | sc-403881-ACT | 20 µg | $397.00 |
CAPN5 encodes calpain 5, a calcium-dependent cysteine protease implicated in regulated proteolysis that shapes cytoskeletal dynamics, membrane trafficking, and signal transduction. Calpain activity can influence pathways linked to cell motility, adhesion, and stress responses through limited cleavage of structural and signaling proteins. Dysregulated calpain protease function has been associated with inflammatory and neurodegenerative processes, and CAPN5 variation has been studied in relation to retinal degeneration phenotypes. CAPN5 expression modulation is therefore useful for dissecting protease-driven remodeling events and calcium-responsive signaling programs in human cells.
Calpain 5 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CAPN5 expression without altering the underlying DNA sequence.
Calpain 5 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CAPN5 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 CAPN5 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Calpain 5 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CAPN5 locus and enabling the study of Calpain 5-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Calpain 5 pathway restoration in tumor cells with silenced or reduced CAPN5 expression.
