Interferon regulatory factor 5 (IRF5) is a transcription factor that integrates pattern-recognition receptor signaling to shape innate and adaptive immune responses. Downstream of Toll-like receptor and RIG-I–like receptor pathways, IRF-5 promotes transcriptional programs linked to type I interferon responses and pro-inflammatory cytokine production, influencing macrophage polarization and B cell activity. IRF5 activity intersects with NF-κB and MAPK signaling and contributes to context-dependent control of apoptosis and cell-state decisions. Genetic and expression variation in IRF5 has been associated with immune dysregulation and susceptibility to autoimmune and inflammatory disease phenotypes, making it a key node for mechanistic studies in immunology.
IRF-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IRF5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IRF5. 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 IRF5 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 IRF5-disrupted clones.
