robo4 CRISPR Activation Plasmid (h): sc-401856-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- robo4 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- robo4 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 robo4 CRISPR Activation Plasmid (h) and robo4 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the ROBO4 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: robo4 Antibody (D-3): sc-166872

ROBO4 (roundabout guidance receptor 4) encodes an endothelial-enriched transmembrane receptor that helps maintain vascular stability and regulates angiogenic behavior. Robo4 modulates cytoskeletal dynamics and endothelial barrier function by influencing guidance and adhesion signaling, including cross-talk with SLIT cues and pathways linked to VEGF-driven permeability. Through these mechanisms, ROBO4 is broadly relevant to processes such as vessel sprouting, vascular inflammation, and leukocyte trafficking within the microvasculature. Dysregulated ROBO4 expression or signaling has been associated with pathological angiogenesis and altered vascular integrity observed across diverse cardiovascular and tumor-associated vascular phenotypes.
robo4 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ROBO4 expression without altering the underlying DNA sequence.
robo4 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ROBO4 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 ROBO4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous robo4 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ROBO4 locus and enabling the study of robo4-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of robo4 pathway restoration in tumor cells with silenced or reduced ROBO4 expression.
