Rock-2 CRISPR Activation Plasmid (m) | sc-422695-ACT | 20 µg | $397.00 |
Mouse Rock2 encodes Rho-associated coiled-coil containing protein kinase 2 (ROCK2), a serine/threonine kinase that functions as a principal effector of RhoA to control actomyosin contractility, stress fiber formation, and focal adhesion dynamics. ROCK2 phosphorylates substrates such as MYPT1 and LIMK, regulating myosin light chain activity and cofilin-dependent actin remodeling to influence cell shape, polarity, and migration. Through these cytoskeletal programs, Rock2 contributes to processes including cytokinesis, neurite outgrowth, and vascular smooth muscle tone, and is frequently studied in the context of fibrosis, inflammation, neurodegeneration, and cancer-related invasion and metastasis. Its pathway connectivity with Rho GTPase signaling and mechanotransduction makes Rock2 a widely used node for dissecting how cytoskeletal tension interfaces with transcriptional and extracellular matrix cues.
Rock-2 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Rock2 expression without altering the underlying DNA sequence.
Rock-2 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Rock2 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the Rock2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Rock-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Rock2 locus and enabling the study of Rock-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Rock-2 pathway restoration in tumor cells with silenced or reduced Rock2 expression.
