FLNB encodes filamin 3, an actin-binding scaffolding protein that crosslinks F-actin and organizes cortical cytoskeletal architecture to coordinate cell shape, polarity, and mechanical stability. Filamin 3 supports integrin-dependent adhesion, receptor clustering, and mechanotransduction by coupling membrane proteins to the actin network and modulating Rho-family GTPase signaling, thereby influencing migration and tissue remodeling. In human biology, disruption of filamin-family function is linked to altered cytoskeletal dynamics and defects in skeletal development, and FLNB variation is associated with inherited skeletal dysplasia phenotypes. These properties make FLNB a useful target for studying force-dependent signaling, cytoskeleton–ECM crosstalk, and developmentally regulated morphogenetic programs.
Filamin 3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FLNB locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FLNB. 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 FLNB 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 FLNB-disrupted clones.
