Rsk-2 CRISPR Activation Plasmid (h) | sc-401003-ACT | 20 µg | $397.00 |
RPS6KA3 encodes ribosomal S6 kinase A3 (Rsk-2), a serine/threonine kinase that acts downstream of ERK1/2 in the MAPK signaling cascade to couple extracellular stimuli to transcriptional and translational control. Rsk-2 phosphorylates nuclear and cytoplasmic substrates implicated in cell-cycle progression, differentiation, and stress-responsive gene expression, including regulators of chromatin and immediate-early transcriptional programs. Through these activities, Rsk-2 contributes to growth factor–dependent signaling, feedback regulation within MAPK pathways, and modulation of protein synthesis. Dysregulation of RPS6KA3/Rsk-2 signaling has been associated with neurodevelopmental and cognitive phenotypes and is also relevant to research on aberrant MAPK-driven proliferation and survival programs.
Rsk-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous RPS6KA3 expression without altering the underlying DNA sequence.
Rsk-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the RPS6KA3 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 RPS6KA3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Rsk-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native RPS6KA3 locus and enabling the study of Rsk-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Rsk-2 pathway restoration in tumor cells with silenced or reduced RPS6KA3 expression.
