CASP3 encodes caspase-3, a central executioner cysteine-aspartate protease that cleaves hundreds of substrates to drive the biochemical and morphological hallmarks of apoptosis. Caspase-3 is activated downstream of intrinsic mitochondrial signaling via Apaf-1/caspase-9 and extrinsic death receptor pathways via caspase-8, integrating stress signals with regulated cell dismantling. Through proteolysis of targets such as PARP1, ICAD, and cytoskeletal components, caspase-3 shapes DNA fragmentation, membrane blebbing, and irreversible commitment to programmed cell death. Dysregulated CASP3 activity is implicated across diverse disease contexts where apoptosis is altered, including cancer cell survival, neurodegeneration, and immune and inflammatory phenotypes.
caspase-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CASP3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CASP3. 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 CASP3 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 CASP3-disrupted clones.
