FMN1 encodes formin 1, a member of the diaphanous-related formin family that nucleates and elongates unbranched actin filaments to organize cytoskeletal architecture. Formin 1 supports dynamic processes including cell polarity, adhesion, migration, and cytokinesis by coordinating actin assembly and cross-talk with Rho-family GTPase signaling and microtubule–actin coupling. Through these functions, FMN1 contributes to tissue morphogenesis and neuronal and mesenchymal cell behaviors where precise actin remodeling is required. Dysregulated formin-driven cytoskeletal control has been associated with altered invasiveness, developmental abnormalities, and other pathology-relevant phenotypes in model systems, motivating mechanistic studies of FMN1-dependent actin dynamics.
Formin 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FMN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FMN1. 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 FMN1 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 FMN1-disrupted clones.
