EGR3 encodes the zinc-finger transcription factor Egr-3, an immediate-early gene product induced by diverse extracellular cues and activity-dependent signaling. Egr-3 regulates stimulus-responsive transcriptional programs that influence cell differentiation, proliferation, and adaptive responses, integrating pathways downstream of MAPK/ERK and calcium-dependent signaling to remodel gene expression. In the nervous and immune systems, Egr-3 contributes to activity-driven plasticity and lymphocyte functional programs, linking transcriptional control to cellular activation states. Dysregulated EGR3 expression has been associated with neuropsychiatric and neurodevelopmental phenotypes and altered immune regulation, making it a useful node for mechanistic studies of stimulus-coupled gene networks.
Egr-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EGR3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EGR3. 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 EGR3 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 EGR3-disrupted clones.
