Mouse Asprv1 encodes SASPase, an aspartic protease best known for its role in epidermal differentiation and barrier formation. SASPase contributes to the proteolytic processing of structural proteins in keratinizing epithelia, supporting cornification and stratum corneum homeostasis. Altered Asprv1 activity has been linked to disrupted keratinization programs and skin barrier dysfunction, making it relevant to studies of epithelial stress responses and inflammatory skin phenotypes. In mouse models, Asprv1 provides a tractable entry point for dissecting protease-regulated pathways that coordinate terminal differentiation and tissue integrity.
SASPase Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Asprv1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Asprv1. 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 Asprv1 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 Asprv1-disrupted clones.
