RRP8 CRISPR Activation Plasmid (m) | sc-430400-ACT | 20 µg | $397.00 |
Mouse Rrp8 encodes RRP8, a conserved nucleolar factor implicated in ribosome biogenesis through roles in pre-rRNA processing and maturation of the small ribosomal subunit. By regulating nucleolar RNA metabolism and supporting translational capacity, RRP8 influences fundamental processes such as cell-cycle progression, growth control, and cellular stress responses. Perturbation of ribosome assembly pathways can remodel gene expression programs and proteostasis, making Rrp8 activity relevant to studies of nucleolar function, proliferation phenotypes, and disease-associated ribosomopathies and cancer-linked alterations in ribosome biogenesis.
RRP8 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Rrp8 expression without altering the underlying DNA sequence.
RRP8 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Rrp8 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 Rrp8 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous RRP8 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Rrp8 locus and enabling the study of RRP8-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of RRP8 pathway restoration in tumor cells with silenced or reduced Rrp8 expression.
