Rtl1 CRISPR Activation Plasmid (m): sc-436156-ACT
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Rtl1 CRISPR Activation Plasmid (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Rtl1 CRISPR Activation Plasmid (m) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by Rtl1 CRISPR Activation Plasmid (m) and Rtl1 CRISPR Activation Plasmid (m2) target distinct regulatory regions upstream of the Rtl1 transcriptional start site. One or both designs may be available

Mouse Rtl1 (retrotransposon-like 1) encodes a paternally expressed, imprinted protein that is highly enriched in the developing placenta and contributes to fetal growth by supporting trophoblast function and placental vascular development. Rtl1 activity is linked to processes governing cell survival, differentiation, and tissue remodeling at the maternal–fetal interface, with downstream effects on nutrient exchange and developmental homeostasis. Dysregulated RTL1 expression has been associated with imprinting defects and abnormal placentation phenotypes, making it relevant to studies of developmental disorders and growth regulation. As an imprinted locus, Rtl1 also serves as a model for investigating epigenetic control, allele-specific expression, and noncanonical regulatory mechanisms in mammalian development.
Rtl1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Rtl1 expression without altering the underlying DNA sequence.
Rtl1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Rtl1 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 Rtl1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Rtl1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Rtl1 locus and enabling the study of Rtl1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Rtl1 pathway restoration in tumor cells with silenced or reduced Rtl1 expression.
