ATF6 (activating transcription factor 6 alpha) is an ER membrane–tethered bZIP transcription factor that functions as a key sensor in the unfolded protein response (UPR). Upon ER stress, ATF-6α translocates to the Golgi for regulated intramembrane proteolysis, releasing an active N-terminal fragment that induces genes involved in proteostasis, ER-associated degradation (ERAD), and chaperone-mediated protein folding. ATF6 signaling integrates with PERK–eIF2α and IRE1–XBP1 branches to coordinate adaptation to secretory load, oxidative stress, and metabolic cues. Dysregulated ATF6 activity has been implicated in conditions featuring chronic proteotoxic stress, including neurodegeneration, diabetes-related β-cell dysfunction, inflammatory states, and cardiomyopathy, making it a valuable node for mechanistic studies in mouse models.
ATF-6α CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Atf6 expression without altering the underlying DNA sequence.
ATF-6α CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Atf6 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 Atf6 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ATF-6α expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Atf6 locus and enabling the study of ATF-6α-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ATF-6α pathway restoration in tumor cells with silenced or reduced Atf6 expression.
