COL17A1 encodes collagen type XVII alpha 1, a transmembrane component of hemidesmosomes that anchors basal keratinocytes to the basement membrane through interactions with laminin-332 and integrins. By stabilizing dermal–epidermal adhesion and organizing extracellular matrix contacts, COL17A1 supports epidermal integrity, mechanical resilience, and epithelial homeostasis. Altered COL17A1 expression or function is linked to skin blistering phenotypes and autoimmune targeting at the dermal–epidermal junction, and it is also studied in the context of epithelial remodeling and tumor invasion. These properties make COL17A1 a useful target for investigating adhesion signaling, matrix–cell interfaces, and junctional stability in human epithelial systems.
COL17A1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the COL17A1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within COL17A1. 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 COL17A1 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 COL17A1-disrupted clones.
