TBK1 Lentiviral Activation Particles (m) | sc-425191-LAC | 200 µl | $455.00 |
Mouse Tbk1 encodes TANK-binding kinase 1 (TBK1), a serine/threonine kinase that integrates innate immune and stress signaling. TBK1 phosphorylates IRF3/IRF7 and interfaces with NF-κB pathways downstream of pattern-recognition receptors such as TLR3/4, RIG-I/MDA5, and cGAS–STING to coordinate type I interferon and inflammatory gene programs. Beyond antiviral responses, TBK1 contributes to selective autophagy and mitophagy through regulation of autophagy adaptors, linking immune signaling to cellular homeostasis. Dysregulated TBK1 activity has been implicated in inflammation-associated phenotypes and neurodegeneration-related pathways, making it relevant for mechanistic studies in immunology, infection biology, and cell stress responses.
TBK1 Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Tbk1 upregulation across a broader range of human cell types.
TBK1 Lentiviral Activation Particles (m) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the Tbk1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous TBK1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Tbk1 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
