Human CAPN1 encodes calpain 1, a calcium-dependent cysteine protease that executes limited proteolysis of cytoskeletal and signaling proteins to modulate adhesion, migration, membrane remodeling, and synaptic function. Calpain 1 activity is tightly controlled by intracellular Ca²⁺ dynamics and its endogenous inhibitor calpastatin, linking CAPN1 to Ca²⁺-regulated signal transduction, focal adhesion turnover, and proteostasis pathways. Dysregulated calpain-mediated cleavage has been associated with neuronal injury responses, neurodegenerative processes, and altered muscle and cytoskeletal homeostasis, making CAPN1 a relevant node for studying stress-dependent remodeling and cell survival programs. CAPN1 perturbation can also influence downstream phosphorylation networks and proteolytic processing events that shape inflammatory and apoptotic signaling cascades.
Calpain 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CAPN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CAPN1. 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 CAPN1 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 CAPN1-disrupted clones.
