BCL9 encodes Bcl-9, a transcriptional co-activator that couples β-catenin to TCF/LEF DNA-binding factors to regulate Wnt/β-catenin–dependent gene expression. Through this interaction, Bcl-9 influences programs controlling cell proliferation, lineage specification, and tissue homeostasis, and it contributes to transcriptional complex assembly at Wnt-responsive enhancers. Dysregulated BCL9 activity is frequently linked to aberrant Wnt signaling outputs observed in multiple cancers, where altered transcriptional control can support tumor progression and invasiveness. As a result, BCL9 is widely studied as a node connecting upstream Wnt pathway activation to downstream oncogenic transcriptional networks.
Bcl-9 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the BCL9 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within BCL9. 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 BCL9 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 BCL9-disrupted clones.
