G3BP1 CRISPR Activation Plasmid (m) | sc-424175-ACT | 20 µg | $397.00 |
Mouse G3BP1 (G3bp1) is an RNA-binding protein that functions as a central nucleator of stress granules and a coordinator of mRNA triage during cellular stress. It integrates signaling from pathways such as eIF2α-dependent translational control and interfaces with innate immune and antiviral responses through regulation of RNA metabolism and ribonucleoprotein assembly. G3BP1 influences cell survival, proliferation, and apoptosis by modulating the stability and translation of transcripts involved in growth and inflammatory programs. Dysregulated G3BP1 activity and stress granule dynamics have been linked to neurodegeneration, viral pathogenesis, and cancer-associated alterations in post-transcriptional regulation, making it a useful node for mechanistic studies of RNA biology.
G3BP1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous G3bp1 expression without altering the underlying DNA sequence.
G3BP1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the G3bp1 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 G3bp1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous G3BP1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native G3bp1 locus and enabling the study of G3BP1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of G3BP1 pathway restoration in tumor cells with silenced or reduced G3bp1 expression.
