Mouse Ctcfl encodes BORIS (Brother of the Regulator of Imprinted Sites), a C2H2 zinc-finger DNA-binding protein related to CTCF that helps shape chromatin architecture and sequence-specific transcriptional programs. BORIS participates in epigenetic regulation through interactions with histone-modifying and chromatin remodeling complexes, influencing promoter/enhancer activity, DNA methylation states, and transcriptional insulation. Altered BORIS expression has been linked to deregulated gene expression patterns observed in germ cell biology and in multiple cancer-associated contexts, making it relevant for studies of chromatin organization, cell identity, and genome stability. Its locus is therefore of interest for investigating how changes in 3D genome regulation and epigenetic control contribute to aberrant transcriptional networks.
BORIS Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Ctcfl locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Ctcfl. 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 Ctcfl 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 Ctcfl-disrupted clones.
