Mouse HACE1 (HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1) encodes an E3 ubiquitin ligase that regulates protein turnover and signaling by catalyzing ubiquitin transfer to specific substrates. HACE1 has been linked to cytoskeletal organization, vesicular trafficking, and stress-response pathways, and it can influence small GTPase-dependent processes that shape cell migration and adhesion. By modulating ubiquitin-dependent quality control and signaling amplitude, HACE1 supports cellular homeostasis in contexts where proteostasis and redox balance are challenged. Altered HACE1 activity has been associated with dysregulated growth control and genome stability phenotypes, making it relevant for mechanistic studies of tumor suppressor-like functions and pathway rewiring in disease models.
HACE1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Hace1 expression without altering the underlying DNA sequence.
HACE1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Hace1 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 Hace1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous HACE1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Hace1 locus and enabling the study of HACE1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of HACE1 pathway restoration in tumor cells with silenced or reduced Hace1 expression.
