TRAF3 CRISPR Activation Plasmid (m) | sc-423494-ACT | 20 µg | $397.00 |
Mouse Traf3 encodes TRAF3, an adaptor and E3 ubiquitin ligase that couples multiple receptors to downstream signaling, including TNF receptor superfamily members, Toll-like receptors, and RIG-I–like receptors. TRAF3 helps balance canonical and non-canonical NF-κB activity and regulates IRF3/IRF7-dependent type I interferon responses through ubiquitin-dependent control of kinase complexes such as TBK1 and IKK. Through these pathways, TRAF3 influences innate and adaptive immune cell activation, cytokine production, and antiviral defense. Dysregulated TRAF3 signaling has been linked to immune imbalance and inflammation-associated phenotypes, making Traf3 a relevant node for mechanistic studies of receptor-proximal signaling and transcriptional programs in mouse models.
TRAF3 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Traf3 expression without altering the underlying DNA sequence.
TRAF3 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Traf3 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 Traf3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous TRAF3 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Traf3 locus and enabling the study of TRAF3-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of TRAF3 pathway restoration in tumor cells with silenced or reduced Traf3 expression.
