FLII encodes Flightless I, an evolutionarily conserved gelsolin family actin-remodeling protein that coordinates cytoskeletal dynamics with transcriptional regulation. Flightless I participates in cell migration, adhesion, and wound-response programs through modulation of actin architecture and interactions with signaling networks such as Rho GTPase-dependent pathways and focal adhesion–associated processes. In the nucleus, it can influence chromatin-associated complexes and transcriptional outputs that shape inflammatory and stress-responsive gene expression. Dysregulated FLII activity has been linked in the literature to altered epithelial repair, immune signaling phenotypes, and tumor-associated cell motility, making it a useful target for mechanistic studies of cytoskeleton-to-nucleus communication.
Flightless I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FLII locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FLII. 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 FLII 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 FLII-disrupted clones.
