CTSC encodes cathepsin C, a lysosomal cysteine dipeptidyl peptidase that removes N-terminal dipeptides to activate multiple granule serine proteases in myeloid lineage cells. Through its role in proteolytic processing, cathepsin C influences innate immune effector functions, inflammatory signaling, and regulated protease cascades within the endolysosomal compartment. CTSC activity is closely tied to neutrophil and macrophage biology, impacting pathways involved in host defense, tissue remodeling, and protease-dependent signaling. Dysregulation of CTSC has been linked to immune and inflammatory phenotypes and provides a mechanistic entry point for studying protease network perturbations in disease-relevant cellular contexts.
cathepsin C Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CTSC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CTSC. 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 CTSC 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 CTSC-disrupted clones.
