Human LIMK2 encodes LIM domain kinase 2 (LIMK-2), a serine/threonine kinase that phosphorylates and inactivates cofilin to regulate actin filament turnover. Through Rho-family GTPase signaling via ROCK and PAK, LIMK-2 coordinates cytoskeletal dynamics underlying cell shape control, adhesion, migration, and cytokinesis. LIMK2 activity contributes to pathways linked to epithelial–mesenchymal transition, mechanotransduction, and synaptic structure, and dysregulation of actin remodeling is associated with invasive behavior and aberrant tissue remodeling phenotypes. Altered LIMK2 signaling has been studied in contexts including cancer cell motility and metastasis-related programs, neurodegenerative processes involving spine dynamics, and fibrotic remodeling where actin–myosin contractility is perturbed.
LIMK-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LIMK2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LIMK2. 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 LIMK2 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 LIMK2-disrupted clones.
