Mouse Smad2 encodes an R-SMAD transcription factor that transduces signals from TGF‑β/Activin receptors to the nucleus, where it cooperates with SMAD4 to regulate context-dependent gene expression programs. Through phosphorylation-dependent complex formation and chromatin engagement, SMAD2 controls processes including epithelial–mesenchymal transition, extracellular matrix remodeling, cell-cycle regulation, and lineage specification during development. Smad2 activity intersects with MAPK and PI3K signaling and is modulated by inhibitory SMADs and ubiquitin-mediated turnover, shaping signal duration and amplitude. Dysregulated TGF‑β/SMAD2 signaling is frequently studied in fibrosis, inflammation, and cancer biology, where pathway balance influences proliferation, differentiation, and invasive phenotypes.
Smad2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Smad2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Smad2. 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 Smad2 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 Smad2-disrupted clones.
