Abin-1 Lentiviral Activation Particles (m) | sc-425441-LAC | 200 µl | $455.00 |
Mouse Tnip1 encodes ABIN-1 (A20-binding inhibitor of NF-κB), a ubiquitin-binding adaptor that modulates inflammatory signaling downstream of receptors such as TNFR and TLRs by coordinating ubiquitin-dependent protein complexes. ABIN-1 interacts with the deubiquitinase A20/TNFAIP3 to restrain NF-κB and MAPK pathway activation, shaping cytokine production, innate immune homeostasis, and cell survival decisions. Dysregulated TNIP1/ABIN-1 function has been linked to aberrant immune activation and inflammatory phenotypes, making it a useful node for studying signal termination, ubiquitin chain recognition, and transcriptional control in immune and stromal cell contexts.
Abin-1 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 Tnip1 upregulation across a broader range of human cell types.
Abin-1 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 Tnip1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Abin-1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Tnip1 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.
