FLI1 encodes Fli-1, an ETS family transcription factor that binds GGAA-containing regulatory elements to control gene programs involved in hematopoietic differentiation, megakaryopoiesis, and endothelial cell function. Fli-1 integrates signaling inputs with chromatin regulation to modulate transcriptional networks governing proliferation, lineage commitment, and vascular homeostasis. Dysregulated FLI1 activity has been implicated in oncogenic transcriptional rewiring and aberrant immune and vascular phenotypes, making it a relevant node for studying transcription factor–driven pathways in human cells. In addition, FLI1 is frequently examined in the context of gene fusion biology and lineage-specific enhancer landscapes that shape cell identity.
Fli-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FLI1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FLI1. 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 FLI1 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 FLI1-disrupted clones.
