Reg IIIγ CRISPR Activation Plasmid (m): sc-422640-ACT
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Reg IIIγ CRISPR Activation Plasmid (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Reg IIIγ CRISPR Activation Plasmid (m) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by Reg IIIγ CRISPR Activation Plasmid (m) and Reg IIIγ CRISPR Activation Plasmid (m2) target distinct regulatory regions upstream of the Reg3g transcriptional start site. One or both designs may be available

Reg3g encodes regenerating islet-derived protein 3 gamma (Reg IIIγ), a secreted C-type lectin enriched in intestinal epithelial and Paneth cell compartments that contributes to mucosal barrier defense by binding bacterial peptidoglycan and shaping host–microbiota interactions. Its expression is strongly induced by cytokine and microbial sensing pathways, including IL-22/STAT3 signaling and Toll-like receptor–dependent innate immune responses, linking Reg IIIγ to epithelial restitution and antimicrobial programs. Altered REG3 family activity has been associated with inflammatory states at barrier surfaces, making Reg3g a useful marker and mechanistic node for studying gut inflammation, dysbiosis, and epithelial stress responses in mouse models.
Reg IIIγ CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Reg3g expression without altering the underlying DNA sequence.
Reg IIIγ CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Reg3g 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 Reg3g transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Reg IIIγ expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Reg3g locus and enabling the study of Reg IIIγ-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Reg IIIγ pathway restoration in tumor cells with silenced or reduced Reg3g expression.
