Human SLFN11 (Schlafen family member 11) encodes Slfn11, an interferon-stimulated protein that links innate immune signaling to regulation of DNA replication and genome stability. Slfn11 modulates replication stress responses by influencing chromatin and replication fork progression, thereby shaping cellular outcomes following genotoxic stress and perturbations in nucleotide metabolism. SLFN11 expression and epigenetic regulation have been studied in the context of tumor biology, where altered Slfn11 activity correlates with changes in proliferative capacity and DNA damage response pathway engagement. As a result, SLFN11 is frequently investigated in mechanisms of replication stress, interferon-driven transcriptional programs, and cellular determinants of genotoxic sensitivity.
Slfn11 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SLFN11 expression without altering the underlying DNA sequence.
Slfn11 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SLFN11 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 SLFN11 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Slfn11 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SLFN11 locus and enabling the study of Slfn11-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Slfn11 pathway restoration in tumor cells with silenced or reduced SLFN11 expression.
