GPR35 CRISPR Activation Plasmid (h) | sc-416792-ACT | 20 µg | $397.00 |
GPR35 encodes a class A G protein-coupled receptor that is enriched in immune and gastrointestinal tissues and couples to heterotrimeric G proteins to regulate intracellular second-messenger signaling. Reported ligands include microbiome- and metabolism-associated small molecules, positioning GPR35 as a sensor linking environmental cues to cellular responses. Downstream pathways commonly involve modulation of cAMP, Ca²⁺ flux, and ERK/MAPK signaling, with effects on chemotaxis, barrier function, and inflammatory mediator production. Altered GPR35 expression or signaling has been associated with inflammatory bowel disease susceptibility and broader immunometabolic phenotypes, supporting its relevance in studies of mucosal immunity and inflammation.
GPR35 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GPR35 expression without altering the underlying DNA sequence.
GPR35 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GPR35 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 GPR35 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GPR35 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GPR35 locus and enabling the study of GPR35-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GPR35 pathway restoration in tumor cells with silenced or reduced GPR35 expression.
