ARRDC4 CRISPR Activation Plasmid (h): sc-406413-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ARRDC4 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- ARRDC4 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 ARRDC4 CRISPR Activation Plasmid (h) and ARRDC4 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the ARRDC4 transcriptional start site. One or both designs may be available

ARRDC4 (arrestin domain containing 4) is a human α-arrestin family adaptor implicated in regulating membrane protein trafficking and signal attenuation by coupling receptors and transporters to endocytic and ubiquitin-dependent pathways. It has been linked to cellular energy and nutrient-stress responses, including modulation of glucose and lipid metabolism through interactions with metabolic signaling networks. ARRDC4 expression is responsive to metabolic cues and may influence receptor turnover and downstream transcriptional programs that shape cellular adaptation to stress. Dysregulated ARRDC4 activity or expression has been investigated in contexts associated with metabolic dysfunction and altered signaling homeostasis relevant to complex disease biology.
ARRDC4 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ARRDC4 expression without altering the underlying DNA sequence.
ARRDC4 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ARRDC4 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 ARRDC4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ARRDC4 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ARRDC4 locus and enabling the study of ARRDC4-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ARRDC4 pathway restoration in tumor cells with silenced or reduced ARRDC4 expression.
