Tak1 CRISPR Activation Plasmid (h) | sc-400364-ACT | 20 µg | $397.00 |
Human MAP3K7 encodes transforming growth factor-β–activated kinase 1 (TAK1), a MAP3K that integrates signals from pro-inflammatory cytokines, Toll-like and IL-1 receptors, and TGF-β family ligands. TAK1 activates downstream NF-κB and MAPK cascades, including p38, JNK, and ERK pathways, thereby regulating transcriptional programs controlling innate immune responses, apoptosis, and stress adaptation. Through its roles in ubiquitin-dependent signaling complexes and kinase-mediated phosphorylation events, TAK1 influences cell fate decisions across many tissue contexts. Dysregulated MAP3K7/TAK1 signaling has been implicated in inflammatory pathobiology and oncogenic processes where altered NF-κB/MAPK activity reshapes survival and cytokine networks.
Tak1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous MAP3K7 expression without altering the underlying DNA sequence.
Tak1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the MAP3K7 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 MAP3K7 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Tak1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native MAP3K7 locus and enabling the study of Tak1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Tak1 pathway restoration in tumor cells with silenced or reduced MAP3K7 expression.
