USP34 encodes a ubiquitin-specific protease that reverses protein ubiquitination to regulate protein stability and signaling output. It has been linked to control of WNT/β-catenin pathway activity through deubiquitination-dependent stabilization of key pathway components, influencing transcriptional programs that govern proliferation and cell fate decisions. USP34 activity also intersects with proteostasis and DNA damage–associated processes via modulation of ubiquitin-dependent turnover and checkpoint signaling. Dysregulated ubiquitin signaling involving USP34 has been associated with altered growth control and genomic maintenance in cancer biology contexts, making it relevant for mechanistic studies of oncogenic pathways.
USP34 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous USP34 expression without altering the underlying DNA sequence.
USP34 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the USP34 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 USP34 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous USP34 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native USP34 locus and enabling the study of USP34-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of USP34 pathway restoration in tumor cells with silenced or reduced USP34 expression.
