ACTN4 encodes α-actinin-4, an actin filament crosslinking protein that organizes cortical cytoskeleton architecture and regulates cell adhesion, spreading, and migration through interactions at focal adhesions and adherens junctions. By linking F-actin to integrin-associated complexes and signaling intermediates, α-actinin-4 contributes to mechanotransduction and dynamic remodeling of the actin network that shapes cell polarity and motility. Altered ACTN4 dosage or activity has been associated with cytoskeletal dysregulation in kidney podocytes and has been studied in contexts such as focal segmental glomerulosclerosis as well as invasion-related phenotypes in cancer cell models. These properties make ACTN4 a widely used target for dissecting actin-dependent pathways, adhesion signaling, and force-responsive transcriptional programs.
α-actinin-4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ACTN4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ACTN4. 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 ACTN4 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 ACTN4-disrupted clones.
