EN1 (Engrailed 1) encodes a homeobox transcription factor that regulates embryonic patterning and neural development by controlling gene expression programs involved in cell fate specification, differentiation, and axon guidance. In human cells, EN1 contributes to transcriptional networks that intersect with developmental signaling pathways such as Wnt/β-catenin and SHH, influencing regional identity and tissue morphogenesis. Dysregulated EN1 expression or epigenetic control has been linked to altered lineage programs and tumor-associated phenotypes in multiple contexts, making it a useful node for studying developmental reactivation and cell-state transitions. EN1 is therefore frequently investigated in models of neurodevelopment, neuronal maintenance, and disease-relevant transcriptional rewiring.
EN1/Engrailed 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EN1. 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 EN1 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 EN1-disrupted clones.
