DRAK2 CRISPR Activation Plasmid (h): sc-404787-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- DRAK2 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- DRAK2 CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by DRAK2 CRISPR Activation Plasmid (h) and DRAK2 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the STK17B transcriptional start site. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: DRAK2 Antibody (C-2): sc-398324

STK17B encodes DRAK2 (DAPK-related apoptosis-inducing kinase 2), a serine/threonine kinase that modulates lymphocyte activation thresholds and integrates signaling downstream of the T cell receptor. DRAK2 has been linked to regulation of apoptosis, mitochondrial stress responses, and phosphorylation-driven control of transcriptional programs that shape immune cell survival and function. Through these roles, STK17B is frequently studied in pathways governing immune tolerance, inflammatory signaling, and cellular stress adaptation. Dysregulated DRAK2 activity and STK17B expression patterns have been associated with immune-mediated disease mechanisms and context-dependent changes in cell survival observed in cancer and inflammation research.
DRAK2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous STK17B expression without altering the underlying DNA sequence.
DRAK2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the STK17B 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 STK17B transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DRAK2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native STK17B locus and enabling the study of DRAK2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DRAK2 pathway restoration in tumor cells with silenced or reduced STK17B expression.
