Tmem173 encodes TMEM173 (also known as STING), an endoplasmic reticulum–resident adaptor that coordinates innate immune sensing of cytosolic DNA. Upon binding cyclic dinucleotides produced by cGAS, TMEM173 drives TBK1–IRF3 signaling and NF-κB activation, promoting type I interferon and inflammatory gene programs. This pathway intersects with autophagy and cell stress responses and shapes antiviral defense, responses to intracellular bacteria, and tumor–immune microenvironment signaling in mouse models. Dysregulated TMEM173 signaling has been linked to aberrant inflammation and autoimmune-like phenotypes, making it a frequent target in studies of immunopathology and host–pathogen interactions.
TMEM173 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Tmem173 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Tmem173. 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 Tmem173 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 Tmem173-disrupted clones.
