TRIM29 Lentiviral Activation Particles (h) | sc-402144-LAC | 200 µl | $455.00 |
TRIM29 (tripartite motif containing 29) encodes an E3 ubiquitin ligase–associated TRIM family protein implicated in regulation of protein stability, cellular stress responses, and epithelial differentiation programs. TRIM29 interfaces with DNA damage response signaling and chromatin-associated processes, influencing transcriptional regulation and cell fate decisions in a context-dependent manner. Altered TRIM29 expression has been reported across multiple cancer types and is studied for roles in tumor progression, invasion, and therapy response mechanisms, as well as broader epithelial homeostasis. These features make TRIM29 a useful target for dissecting ubiquitin-linked regulation, genome integrity pathways, and oncogenic signaling networks in human cell models.
TRIM29 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient TRIM29 upregulation across a broader range of human cell types.
TRIM29 Lentiviral Activation Particles (h) 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 TRIM29 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous TRIM29 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native TRIM29 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.
