RyR CRISPR Activation Plasmid (h) | sc-402986-ACT | 20 µg | $397.00 |
Human RYR2 encodes the ryanodine receptor 2 (RyR2), a large sarcoplasmic/endoplasmic reticulum Ca²⁺ release channel that coordinates excitation–contraction coupling by shaping cytosolic calcium transients. RyR2 activity integrates signaling inputs from cAMP/PKA and CaMKII pathways and interfaces with calcium-induced calcium release, mitochondrial metabolism, and downstream transcriptional programs. Perturbation of RYR2 expression or channel regulation disrupts Ca²⁺ homeostasis, promoting aberrant calcium waves and altered electrophysiological signaling in cardiomyocytes. RYR2 dysfunction is linked to inherited and acquired cardiac rhythm phenotypes, making it a key node for mechanistic studies of calcium handling and cellular stress responses.
RyR-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous RYR2 expression without altering the underlying DNA sequence.
RyR-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the RYR2 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 RYR2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous RyR-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native RYR2 locus and enabling the study of RyR-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of RyR-2 pathway restoration in tumor cells with silenced or reduced RYR2 expression.
