SERPINC1 encodes antithrombin III (ATIII), a secreted serine protease inhibitor that limits coagulation by inactivating thrombin and activated factors such as FXa and FIXa, with activity potentiated by heparan sulfate and heparin. ATIII is a central regulator of hemostasis and interfaces with protease cascades controlling fibrin formation, endothelial homeostasis, and inflammation-linked coagulation signaling. Variation or reduced functional activity in SERPINC1 is associated with dysregulated coagulation and thrombotic predisposition, making it a key locus for studying anticoagulant pathway balance. Because ATIII is produced primarily by hepatocytes and circulates systemically, SERPINC1 is also relevant for investigating secretory protein biogenesis and extracellular protease control in plasma.
ATIII Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SERPINC1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SERPINC1. 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 SERPINC1 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 SERPINC1-disrupted clones.
