Isg15 encodes ISG15, a ubiquitin-like modifier that is rapidly induced by type I interferons and other innate immune stimuli. Through covalent conjugation to substrates (ISGylation) and noncovalent regulatory interactions, ISG15 influences antiviral defense, protein stability, and inflammatory signaling, intersecting with JAK–STAT-driven interferon-stimulated gene programs and ubiquitin–proteasome-associated pathways. In mouse models, altered ISG15 activity is linked to changes in host–pathogen responses, cytokine balance, and immune cell function, making it a useful node for studying interferon biology and inflammation-associated phenotypes.
ISG15 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Isg15 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Isg15. 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 Isg15 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 Isg15-disrupted clones.
