IP Receptor CRISPR Activation Plasmid (h) | sc-404135-ACT | 20 µg | $397.00 |
PTGIR encodes the human prostacyclin (IP) receptor, a G protein–coupled receptor that binds prostacyclin (PGI2) to regulate vasodilatory and anti-aggregatory signaling. Upon activation, IP receptor primarily couples to Gs to elevate cAMP and engage PKA/CREB-dependent transcriptional programs, with additional context-dependent coupling that can influence calcium signaling and MAPK pathways. This receptor integrates arachidonic acid–derived eicosanoid signaling to shape endothelial–platelet interactions, vascular tone, and inflammatory responses. Dysregulated PTGIR/IP signaling has been implicated in cardiovascular and thromboinflammatory phenotypes and is frequently studied in models of vascular dysfunction and immune-mediated tissue injury.
IP Receptor CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous PTGIR expression without altering the underlying DNA sequence.
IP Receptor CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the PTGIR 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 PTGIR transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous IP Receptor expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native PTGIR locus and enabling the study of IP Receptor-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of IP Receptor pathway restoration in tumor cells with silenced or reduced PTGIR expression.
