Human IRAK3 encodes IRAK-M, a kinase-like adaptor that functions as a negative regulator of Toll-like receptor (TLR) and IL-1 receptor signaling in innate immune cells. By restraining MyD88-dependent signaling, IRAK-M limits downstream NF-κB and MAPK activation and helps shape cytokine output, endotoxin tolerance, and resolution of inflammatory responses. IRAK-M activity is linked to macrophage polarization and control of antimicrobial programs, integrating cues that influence tissue inflammation and immune homeostasis. Dysregulated IRAK3/IRAK-M expression has been associated with altered inflammatory signaling in contexts such as sepsis, chronic infection, autoimmune inflammation, and tumor-associated myeloid immunosuppression.
IRAK-M Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IRAK3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IRAK3. 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 IRAK3 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 IRAK3-disrupted clones.
