KRT13 encodes cytokeratin 13, a type I intermediate filament protein that pairs with keratin partners to form the cytoskeletal network characteristic of non-cornified stratified epithelia. Cytokeratin 13 contributes to epithelial structural integrity, cell–cell adhesion, and stress resilience by organizing filament assembly and coordinating with desmosomal and hemidesmosomal complexes. Its expression is regulated during epithelial differentiation and remodeling programs that intersect with wound response and barrier maintenance. Altered KRT13 expression patterns are studied in epithelial dysplasia and carcinoma-associated differentiation changes, making it a useful marker for investigating keratinization state and epithelial lineage plasticity.
Cytokeratin 13 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the KRT13 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within KRT13. 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 KRT13 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 KRT13-disrupted clones.
