EDG-6 CRISPR Activation Plasmid (h) | sc-404415-ACT | 20 µg | $397.00 |
S1PR4 (EDG-6) encodes a sphingosine-1-phosphate (S1P) G protein-coupled receptor with prominent functions in immune and hematopoietic compartments. EDG-6 couples to downstream signaling nodes including PI3K–AKT, MAPK/ERK, and Rho family GTPases to regulate chemotaxis, cytoskeletal remodeling, cytokine programs, and cell survival. Through S1P-dependent control of leukocyte trafficking and inflammatory signaling, S1PR4 is used to study immune homeostasis, myeloid cell biology, and receptor-driven transcriptional responses. Dysregulated S1P–S1PR axis activity has been associated with inflammatory pathophysiology and tumor microenvironment processes, supporting mechanistic investigations of immune modulation and oncogenic signaling networks.
EDG-6 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous S1PR4 expression without altering the underlying DNA sequence.
EDG-6 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the S1PR4 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 S1PR4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous EDG-6 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native S1PR4 locus and enabling the study of EDG-6-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of EDG-6 pathway restoration in tumor cells with silenced or reduced S1PR4 expression.
