Shh CRISPR Activation Plasmid (m): sc-422926-ACT
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Shh CRISPR Activation Plasmid (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Shh 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 Shh CRISPR Activation Plasmid (m) and Shh CRISPR Activation Plasmid (m2) target distinct regulatory regions upstream of the Shh transcriptional start site. One or both designs may be available

Sonic hedgehog (Shh) is a secreted morphogen that orchestrates embryonic patterning and postnatal tissue homeostasis by regulating cell fate specification, proliferation, and differentiation. In mouse, SHH signaling is transduced through PTCH1/SMO to modulate GLI transcription factors, integrating with ciliary trafficking, gradient formation, and developmental gene regulatory networks. Perturbation of SHH pathway activity influences neurodevelopmental processes, limb and craniofacial morphogenesis, and epithelial–mesenchymal interactions. Dysregulated SHH signaling is widely used as a mechanistic model for studying congenital malformations and hedgehog-driven oncogenic programs in diverse tissue contexts.
Shh CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Shh expression without altering the underlying DNA sequence.
Shh CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Shh 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 Shh transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Shh expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Shh locus and enabling the study of Shh-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Shh pathway restoration in tumor cells with silenced or reduced Shh expression.
