Cxadr encodes the coxsackievirus and adenovirus receptor (CAR), an immunoglobulin superfamily cell-adhesion molecule concentrated at epithelial and endothelial tight junctions. CAR contributes to intercellular adhesion, apical–basolateral polarity, and junctional organization through interactions with scaffold proteins and cytoskeletal regulators, linking it to pathways governing barrier integrity and tissue morphogenesis. In mouse models, altered CAR expression or localization is studied in the context of viral entry biology, cardiac development and conduction, and epithelial homeostasis, making Cxadr a useful node for investigating host–pathogen interactions and junction-dependent signaling.
CAR Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Cxadr locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Cxadr. 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 Cxadr 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 Cxadr-disrupted clones.
