SIRT3 CRISPR Activation Plasmid (m) | sc-425704-ACT | 20 µg | $397.00 |
Mouse Sirt3 encodes the mitochondrial NAD+-dependent deacetylase SIRT3, a central regulator of oxidative metabolism and mitochondrial protein homeostasis. SIRT3 deacetylates enzymes involved in the TCA cycle, fatty acid β-oxidation, and the electron transport chain, thereby shaping ATP production and reactive oxygen species control. Through modulation of antioxidant defenses and mitochondrial stress responses, SIRT3 influences pathways linked to metabolic adaptation, inflammation, and cellular survival. Altered SIRT3 activity has been associated with phenotypes relevant to metabolic dysfunction, neurodegeneration, cardiac stress, and cancer biology in experimental models.
SIRT3 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Sirt3 expression without altering the underlying DNA sequence.
SIRT3 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Sirt3 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 Sirt3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous SIRT3 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Sirt3 locus and enabling the study of SIRT3-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of SIRT3 pathway restoration in tumor cells with silenced or reduced Sirt3 expression.
