GPR35 Lentiviral Activation Particles (h) | sc-416792-LAC | 200 µl | $455.00 |
GPR35 encodes a rhodopsin-like G protein-coupled receptor that functions as a chemosensor in immune and gastrointestinal tissues, coupling primarily to Gi/o signaling to modulate cAMP, calcium flux, and downstream MAPK pathways. Reported ligands include microbiota- and metabolism-associated small molecules, positioning GPR35 at the interface of environmental sensing and inflammatory regulation. In human cells, GPR35 activity influences leukocyte trafficking, epithelial barrier responses, and cytokine signaling programs that shape mucosal homeostasis. Altered GPR35 expression or signaling has been associated with inflammatory bowel disease–related mechanisms and tumor microenvironment biology, supporting its use in studies of immunometabolism and GPCR signaling networks.
GPR35 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient GPR35 upregulation across a broader range of human cell types.
GPR35 Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the GPR35 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous GPR35 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native GPR35 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
