RUNX1T1 (ETO) encodes a nuclear transcriptional corepressor that partners with DNA-binding transcription factors to modulate gene expression programs controlling hematopoietic differentiation and lineage commitment. ETO contains Nervy homology regions that recruit NCoR/SMRT–HDAC complexes and other chromatin regulators, linking RUNX1T1 to epigenetic silencing, transcriptional repression, and remodeling of enhancer activity. Dysregulated RUNX1T1 function is strongly implicated in leukemogenesis, most notably through RUNX1–RUNX1T1 fusions that perturb RUNX1-dependent transcriptional networks and block myeloid maturation. These pathways make RUNX1T1 a useful target for studying transcriptional repression mechanisms, chromatin-state dynamics, and altered differentiation programs in cancer-relevant cellular models.
ETO Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RUNX1T1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RUNX1T1. 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 RUNX1T1 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 RUNX1T1-disrupted clones.
