CTSH encodes cathepsin H, a lysosomal cysteine protease that functions primarily as an aminopeptidase and contributes to the terminal steps of intracellular protein turnover. It participates in endolysosomal trafficking and proteolytic processing, influencing antigen processing, extracellular matrix remodeling, and regulation of peptide hormone or growth factor availability in specific cell contexts. Dysregulated cathepsin activity has been linked to altered proteostasis, inflammatory signaling, and invasive cell behaviors, making CTSH a common target in studies of lysosome-dependent stress responses. CTSH expression and activity are also investigated in tumor biology and immune cell function where lysosomal protease balance can modulate microenvironmental interactions.
cathepsin H Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CTSH locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CTSH. 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 CTSH 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 CTSH-disrupted clones.
