IFNAR1 encodes interferon alpha/beta receptor alpha (IFN-α/βRα), a cell-surface subunit of the type I interferon receptor that binds IFN-α and IFN-β to initiate innate immune signaling. Ligand engagement promotes activation of the JAK1/TYK2 kinases and downstream STAT1/STAT2–IRF9 (ISGF3) complexes, driving transcription of interferon-stimulated genes that regulate antiviral defense, antigen presentation, and immune-cell crosstalk. IFNAR1 activity is also shaped by receptor internalization and ubiquitin-mediated turnover, influencing signaling amplitude and duration. Dysregulated type I interferon pathways involving IFNAR1 are widely studied in inflammatory and autoimmune contexts as well as tumor–immune interactions and host–pathogen response phenotypes.
IFN-α/βRα Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IFNAR1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IFNAR1. 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 IFNAR1 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 IFNAR1-disrupted clones.
