BTG4 CRISPR Activation Plasmid (h): sc-408621-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- BTG4 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- BTG4 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 BTG4 CRISPR Activation Plasmid (h) and BTG4 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the BTG4 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: BTG4 Antibody (NB-B3): sc-134287

BTG4 (B-cell translocation gene 4) encodes an antiproliferative BTG/Tob family protein implicated in regulating mRNA metabolism and transcriptional programs that shape cell-cycle progression and differentiation. In human cells, BTG4 has been linked to control of maternal mRNA deadenylation and translational repression, coupling post-transcriptional gene regulation to developmental timing and cell fate transitions. Through interactions with CCR4–NOT deadenylase components and related RNA regulatory factors, BTG4 can influence global transcript stability and proteome output, processes frequently perturbed in oncogenic transformation. Altered BTG family activity is associated with dysregulated growth control and stress-response pathways, making BTG4 a relevant node for mechanistic studies in proliferation, differentiation, and RNA turnover.
BTG4 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous BTG4 expression without altering the underlying DNA sequence.
BTG4 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the BTG4 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 BTG4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous BTG4 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native BTG4 locus and enabling the study of BTG4-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of BTG4 pathway restoration in tumor cells with silenced or reduced BTG4 expression.
