CXCR3 encodes CXCR-3, a G protein–coupled chemokine receptor that binds interferon-inducible ligands including CXCL9, CXCL10, and CXCL11 to direct leukocyte chemotaxis. Upon activation, CXCR-3 couples primarily to Gi signaling to regulate calcium flux, PI3K/AKT and MAPK pathways, integrin activation, and cytoskeletal remodeling that control cell migration and tissue homing. CXCR-3 is a key node in type I/II interferon–driven inflammatory circuits, shaping Th1 polarization and trafficking of activated T cells and NK cells. Dysregulated CXCR3 signaling has been associated with chronic inflammatory and autoimmune conditions, transplant-related immune responses, and tumor immune microenvironment dynamics.
CXCR-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CXCR3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CXCR3. 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 CXCR3 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 CXCR3-disrupted clones.
