RRP8 Lentiviral Activation Particles (m) | sc-430400-LAC | 200 µl | $455.00 |
Mouse Rrp8 encodes RRP8, a nucleolar RNA methyltransferase implicated in ribosome biogenesis through maturation and processing of pre-rRNA and assembly of functional ribosomal subunits. By supporting accurate rRNA modification and nucleolar homeostasis, RRP8 influences global translation capacity, cell-cycle progression, and cellular responses to growth and stress cues. Perturbation of ribosome biogenesis factors is commonly linked to nucleolar stress and altered proteostasis, processes that are frequently studied in the context of developmental defects and cancer-associated dysregulation. RRP8 therefore provides a useful node for investigating pathways that couple rRNA processing to proliferation, genome stability, and transcriptional programs.
RRP8 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 Rrp8 upregulation across a broader range of human cell types.
RRP8 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 Rrp8 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous RRP8 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Rrp8 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.
