Mouse Smarca2 encodes Brm (SMARCA2), an ATP-dependent helicase subunit of the SWI/SNF (BAF) chromatin remodeling complex that repositions nucleosomes to regulate transcriptional programs. Brm helps coordinate enhancer and promoter accessibility for pathways controlling cell-cycle progression, lineage specification, DNA damage responses, and differentiation. Altered SWI/SNF activity, including disruption of SMARCA2/BRM function or complex composition, is linked to epigenetic dysregulation observed across multiple disease-relevant contexts such as cancer biology and neurodevelopmental processes. Smarca2 is therefore widely studied for its role in chromatin architecture, transcription factor cooperativity, and genome stability in mammalian cells.
Brm Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Smarca2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Smarca2. 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 Smarca2 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 Smarca2-disrupted clones.
