FHL3 encodes four-and-a-half LIM domains protein 3 (FHL-3), a LIM-only adaptor that organizes multiprotein complexes and tunes signal transduction and cytoskeletal programs. FHL-3 participates in transcriptional control and mechanotransduction by coupling LIM-domain interactions to pathways including MAPK signaling and regulation of cell-cycle and differentiation gene expression. Through these scaffold functions, FHL-3 influences cell adhesion, migration, and stress-responsive remodeling in diverse cell types. Dysregulated FHL3 expression or altered LIM-mediated interactions have been associated with changes in tumor cell behavior and cardiovascular or skeletal muscle-related phenotypes, making it relevant for mechanistic studies of disease-linked signaling networks.
FHL-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FHL3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FHL3. 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 FHL3 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 FHL3-disrupted clones.
