Mouse Nr4a1 encodes the orphan nuclear receptor Nur77 (NR4A1), an immediate-early transcription factor that integrates signals from T cell receptor activation, MAPK cascades, and NF-κB–linked inflammatory programs. Nur77 regulates gene networks controlling thymocyte negative selection, peripheral T cell anergy, macrophage polarization, and metabolic adaptation, with context-dependent effects on apoptosis and mitochondrial pathways. In the nervous system it is rapidly induced by neuronal activity and stress hormones, linking calcium-dependent signaling to transcriptional responses. Dysregulated NR4A1 signaling has been implicated in models of autoimmunity and chronic inflammation, atherosclerosis, cancer cell survival programs, and neuroinflammatory and neurodegenerative processes.
Nur77 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Nr4a1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Nr4a1. 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 Nr4a1 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 Nr4a1-disrupted clones.
