DACH1 CRISPR Activation Plasmid (h) | sc-404712-ACT | 20 µg | $397.00 |
DACH1 (Dachshund family transcription factor 1) encodes a nuclear DNA-binding regulator that modulates developmental patterning programs and cell fate decisions by coordinating transcriptional networks. In human cells, DACH1 influences proliferation, differentiation, and epithelial–mesenchymal state through interactions with hormone receptor signaling and chromatin-associated regulatory complexes, impacting pathways that govern cell cycle progression and lineage commitment. Dysregulated DACH1 expression or activity has been linked to altered tissue homeostasis and tumor-associated phenotypes in multiple cancer contexts, where it can affect invasion, growth control, and transcriptional programs. As a pathway node integrating developmental transcription with oncogenic signaling, DACH1 is frequently investigated in studies of transcriptional regulation, cellular plasticity, and context-dependent gene network rewiring.
DACH1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DACH1 expression without altering the underlying DNA sequence.
DACH1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DACH1 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 DACH1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DACH1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DACH1 locus and enabling the study of DACH1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DACH1 pathway restoration in tumor cells with silenced or reduced DACH1 expression.
