CTSZ encodes cathepsin Z, a lysosomal cysteine protease that contributes to intracellular protein turnover and peptide processing within the endo-lysosomal system. Beyond its proteolytic role, cathepsin Z can influence cell–matrix interactions and immune cell functions through regulation of adhesion, migration, and antigen-processing-associated pathways. Altered CTSZ expression or activity has been reported in contexts of inflammation and tumor biology, where lysosomal remodeling and extracellular matrix dynamics shape cellular behavior. As a result, CTSZ is frequently studied in mechanisms linking protease-dependent signaling to immune regulation and microenvironmental remodeling.
cathepsin Z Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CTSZ locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CTSZ. 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 CTSZ 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 CTSZ-disrupted clones.
