Human CNN2 encodes calponin 2, an actin-binding regulatory protein that modulates cytoskeletal organization, contractility, and cell shape by influencing actomyosin interactions in smooth muscle and non-muscle cells. Calponin 2 contributes to processes including cell adhesion, migration, and mechanotransduction, linking actin dynamics to signaling networks such as Rho GTPase–dependent pathways. Altered CNN2 expression or calponin-mediated cytoskeletal remodeling has been investigated in contexts of vascular remodeling, inflammation-associated cell motility, and tumor cell invasion, where actin regulation can affect tissue architecture and cell behavior. These features make CNN2 a useful target for studying cytoskeletal control of cellular mechanics and stress-responsive phenotypes.
Calponin 2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CNN2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CNN2. 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 CNN2 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 CNN2-disrupted clones.
