Mouse Casp9 encodes caspase-9, an initiator cysteine-aspartate protease that is activated in the intrinsic mitochondrial apoptosis pathway following cytochrome c release and apoptosome assembly with APAF1. Activated caspase-9 cleaves effector caspases such as caspase-3 and caspase-7, coordinating programmed cell death, mitochondrial stress responses, and developmental tissue remodeling. Caspase-9 activity is modulated by BCL-2 family proteins and inhibitor of apoptosis proteins, linking it to DNA damage signaling, ER stress, and oxidative stress pathways. Dysregulated CASP9-dependent apoptosis has been implicated in cancer biology, neurodegeneration, and immune homeostasis, making Casp9 a key node for studying cell fate decisions in mouse models.
caspase-9 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Casp9 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Casp9. 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 Casp9 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 Casp9-disrupted clones.
