Filamin 1 Double Nickase Plasmid (m) | sc-431396-NIC | 20 µg | $410.00 |
Mouse Flna encodes filamin 1, a large actin-binding scaffold that crosslinks F-actin networks and coordinates membrane receptor signaling with cytoskeletal remodeling. Filamin 1 regulates cell shape, adhesion, and mechanotransduction by organizing complexes involving integrins, small GTPases, and diverse transmembrane receptors, thereby influencing migration and tissue morphogenesis. In multiple cell types, FLNA-dependent cytoskeletal dynamics intersect with pathways controlling focal adhesion turnover and force transmission, making Flna a key determinant of polarity and motility programs. Disruption or altered regulation of filamin 1 has been associated with developmental abnormalities and disease-relevant phenotypes linked to aberrant cell migration and vascular or connective tissue defects, supporting its use as a mechanistic node in cytoskeleton-focused studies.
Filamin 1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Flna locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Flna. 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 Flna 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 Flna-disrupted clones.
