Ataxin-2 CRISPR Activation Plasmid (h) | sc-403590-ACT | 20 µg | $397.00 |
ATXN2 encodes Ataxin-2, an RNA-binding protein that associates with polyribosomes and stress granules to regulate mRNA stability, translation, and cellular responses to stress. Through interactions with RNA metabolism factors and translational control machinery, Ataxin-2 influences proteostasis and signaling programs that shape neuronal and metabolic homeostasis. Altered ATXN2 function and expression are implicated in neurodegenerative phenotypes, including spinocerebellar ataxia type 2 and genetic risk modification in amyotrophic lateral sclerosis, linking this protein to pathways governing synaptic integrity and stress-adaptive translation. As a node connecting RNA processing and stress-response biology, ATXN2 is widely studied in models of neurotoxicity, protein aggregation, and cellular homeostasis.
Ataxin-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ATXN2 expression without altering the underlying DNA sequence.
Ataxin-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ATXN2 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 ATXN2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Ataxin-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ATXN2 locus and enabling the study of Ataxin-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Ataxin-2 pathway restoration in tumor cells with silenced or reduced ATXN2 expression.
