Mouse Ddx58 encodes RIG-I, a cytosolic DExD/H-box RNA helicase that functions as a pattern-recognition receptor for viral RNA species bearing 5′-triphosphate ends and short double-stranded RNA. Ligand binding triggers conformational activation and signaling through MAVS, promoting TBK1/IKKε and IRF3/IRF7 as well as NF-κB pathways to drive type I interferon and inflammatory gene programs. RIG-I activity shapes innate immune crosstalk with antigen presentation, cytokine networks, and cell-intrinsic antiviral restriction. Dysregulated Ddx58/RIG-I signaling is implicated in aberrant interferon responses and inflammation-associated phenotypes, supporting mechanistic studies of immune homeostasis and infection biology in murine systems.
RIG-I Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Ddx58 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Ddx58. 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 Ddx58 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 Ddx58-disrupted clones.
