CASP7 encodes caspase-7, an executioner cysteine-aspartate protease that is activated downstream of initiator caspases during intrinsic and extrinsic apoptotic signaling. Once processed, caspase-7 cleaves a broad set of substrates to drive chromatin condensation, cytoskeletal remodeling, and orderly dismantling of the cell, functioning in concert with caspase-3. CASP7 activity interfaces with mitochondrial stress responses, death receptor pathways, and inflammatory contexts where apoptotic proteolysis shapes tissue homeostasis. Dysregulated caspase-7 signaling has been associated with altered cell death thresholds observed across cancer biology, neurodegeneration, and immune-related pathologies, making it a useful node for mechanistic apoptosis studies.
caspase-7 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CASP7 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CASP7. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt CASP7 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of CASP7-disrupted clones.
