GPR88 CRISPR Activation Plasmid (h) | sc-403566-ACT | 20 µg | $397.00 |
GPR88 encodes an orphan G protein-coupled receptor that is highly enriched in striatal medium spiny neurons and helps tune neuronal excitability and synaptic transmission. Through coupling to heterotrimeric G proteins, GPR88 is linked to modulation of cAMP-dependent signaling, downstream kinase cascades, and activity-dependent transcriptional programs that shape corticostriatal circuit function. Altered GPR88 expression or signaling has been associated with neuropsychiatric and neurodevelopmental phenotypes, including changes in motor control, reward-related behaviors, and cognitive processes. These features make GPR88 a useful target for dissecting GPCR-regulated pathways in human neuronal models and for studying gene network responses in striatal lineage cells.
GPR88 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GPR88 expression without altering the underlying DNA sequence.
GPR88 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GPR88 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 GPR88 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GPR88 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GPR88 locus and enabling the study of GPR88-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GPR88 pathway restoration in tumor cells with silenced or reduced GPR88 expression.
