EGR4 encodes Egr-4, an immediate-early zinc finger transcription factor induced by extracellular stimuli such as growth factors and neuronal activity. Egr-4 regulates gene expression programs involved in cell differentiation, synaptic plasticity, and reproductive axis function, integrating upstream signaling from MAPK/ERK and other activity-dependent pathways. In human biology, EGR4 has been linked to neural development and gonadal function, and altered EGR family transcriptional responses are studied in contexts of neuropsychiatric phenotypes and tumor-associated transcriptional rewiring. As a stimulus-responsive regulator, Egr-4 is frequently used as a readout and node for dissecting transcriptional networks governing cell state transitions.
Egr-4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EGR4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EGR4. 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 EGR4 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 EGR4-disrupted clones.
