ACTA2 encodes α-smooth muscle actin (ACTA2), a core contractile filament protein enriched in vascular smooth muscle cells and myofibroblasts. By polymerizing into F-actin stress fibers and engaging myosin motors, ACTA2 supports cytoskeletal tension, focal adhesion dynamics, and mechanotransduction programs that shape cell migration and extracellular matrix remodeling. ACTA2 activity intersects with RhoA/ROCK signaling, TGF-β–driven differentiation, and SRF/MRTF transcriptional control of contractile gene expression. Dysregulation or mutation of ACTA2 is implicated in vascular smooth muscle dysfunction and remodeling phenotypes, including thoracic aortic aneurysm/dissection risk, and is widely studied in contexts of fibrosis and abnormal contractility.
ACTA2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ACTA2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ACTA2. 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 ACTA2 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 ACTA2-disrupted clones.
