Deltex-1 CRISPR Activation Plasmid (h) | sc-404446-ACT | 20 µg | $397.00 |
Human DTX1 encodes Deltex-1, an E3 ubiquitin ligase that functions as a key modulator of Notch receptor signaling and downstream transcriptional programs that govern cell fate decisions, differentiation, and immune regulation. Through ubiquitin-dependent control of Notch pathway components, Deltex-1 influences signal duration and intensity, intersecting with proteostasis and transcriptional regulatory networks. Altered DTX1/Deltex-1 activity has been associated with dysregulated Notch signaling contexts relevant to hematopoietic and immune cell biology, and it is frequently investigated in models of oncogenic pathway rewiring and inflammatory signaling. These properties make DTX1 a useful target for mechanistic studies linking ubiquitination to pathway-dependent phenotypes.
Deltex-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DTX1 expression without altering the underlying DNA sequence.
Deltex-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DTX1 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 DTX1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Deltex-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DTX1 locus and enabling the study of Deltex-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Deltex-1 pathway restoration in tumor cells with silenced or reduced DTX1 expression.
