LIMK1 encodes LIMK-1, a serine/threonine kinase that regulates actin cytoskeleton dynamics by phosphorylating and inhibiting cofilin, thereby controlling filament turnover, stress fiber assembly, and cell motility. LIMK-1 functions downstream of Rho family GTPase signaling through ROCK and PAK pathways, integrating cues that shape adhesion, migration, and neurite outgrowth. Through its role in cytoskeletal remodeling, LIMK1 is studied in processes such as synaptic plasticity and morphogenesis, and its dysregulation has been implicated in oncogenic invasion programs and neurodevelopmental phenotypes. These pathway connections make LIMK1 a useful target for dissecting actin-dependent signaling networks and cytoskeleton-driven cell behaviors.
LIMK-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LIMK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LIMK1. 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 LIMK1 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 LIMK1-disrupted clones.
