Human ROCK1 encodes Rho-associated protein kinase 1 (Rock-1), a serine/threonine kinase that acts as a major effector of RhoA to regulate actin–myosin contractility, stress fiber formation, focal adhesion dynamics, and cell polarity. Rock-1 phosphorylates substrates such as MYPT1 and LIMK, linking Rho GTPase signaling to myosin light chain phosphorylation, cofilin regulation, and cytoskeletal remodeling during migration, cytokinesis, and apoptosis. Through these processes, ROCK1 influences epithelial–mesenchymal plasticity, barrier function, and mechanotransduction pathways including YAP/TAZ-responsive programs. Dysregulated ROCK1 activity has been associated with pathological tissue remodeling, fibrosis, vascular dysfunction, and tumor cell invasion and metastasis, making it a widely studied node in cytoskeletal and Rho/ROCK pathway research.
Rock-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ROCK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ROCK1. 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 ROCK1 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 ROCK1-disrupted clones.
