GFI1 encodes the transcriptional repressor Gfi-1, a nuclear zinc-finger protein that shapes hematopoietic lineage commitment and preserves stem and progenitor cell homeostasis. Gfi-1 regulates gene expression programs through recruitment of corepressor complexes and chromatin-modifying enzymes, influencing differentiation, cell-cycle control, and apoptosis in developing immune cells. This factor is tightly linked to granulocytic and lymphoid development, and perturbation of GFI1-dependent transcriptional networks has been associated with dysregulated hematopoiesis and altered immune function. As a node in transcriptional and epigenetic control pathways, GFI1 is frequently studied for its roles in oncogenic signaling contexts and stress responses in blood and bone marrow systems.
Gfi-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GFI1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GFI1. 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 GFI1 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 GFI1-disrupted clones.
