CTSE encodes human cathepsin E, an intracellular aspartic protease primarily localized to endosomal and lysosomal compartments where it contributes to proteolytic processing of internalized proteins and peptide antigens. By shaping the endolysosomal protease network, cathepsin E influences antigen presentation, epithelial homeostasis, and inflammatory signaling, with functional links to gastric mucosal biology and immune cell activation. Altered CTSE expression and protease activity have been reported in multiple pathophysiological contexts, including mucosal injury, inflammation, and cancer-associated remodeling of proteolysis. These features make CTSE a useful node for studying lysosome-associated proteostasis, antigen processing pathways, and disease-relevant protease dysregulation.
cathepsin E Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CTSE locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CTSE. 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 CTSE 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 CTSE-disrupted clones.
