MECOM encodes the transcription factor Evi-1, a zinc finger protein that regulates gene expression programs controlling hematopoietic stem and progenitor cell self-renewal, lineage commitment, and survival. Evi-1 interfaces with core transcriptional and epigenetic regulators and modulates signaling outputs including TGF-β/SMAD and JAK/STAT-related pathways, shaping proliferation and differentiation states. Dysregulated MECOM/Evi-1 activity is strongly associated with leukemogenesis and aberrant myeloid differentiation, and it has been implicated more broadly in oncogenic transcriptional networks. Experimental perturbation of Evi-1 supports studies of transcriptional control, chromatin-dependent regulation, and mechanisms of malignant transformation in human cell models.
Evi-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MECOM locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MECOM. 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 MECOM 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 MECOM-disrupted clones.
