CBFA2T3 encodes ETO-2, a nuclear transcriptional corepressor that partners with sequence-specific DNA-binding factors to regulate hematopoietic gene expression and lineage commitment. ETO-2 functions within multiprotein repression complexes that commonly include N-CoR/SMRT, HDACs, and other chromatin modifiers, linking signal-dependent transcription to epigenetic control. Through interactions with RUNX family proteins and related transcriptional regulators, ETO-2 helps coordinate programs governing proliferation, differentiation, and apoptosis in blood and immune cell contexts. Altered CBFA2T3/ETO-2 activity and dysregulated corepressor networks are associated with hematologic malignancy-relevant transcriptional states, making it a useful target for studying oncogenic transcriptional circuitry.
ETO-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CBFA2T3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CBFA2T3. 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 CBFA2T3 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 CBFA2T3-disrupted clones.
