KLF17 (Krüppel-like factor 17) is a zinc-finger transcription factor that regulates epithelial differentiation programs and transcriptional networks controlling cell adhesion, polarity, and motility. By modulating gene expression through GC-rich promoter binding, KLF17 interfaces with pathways linked to epithelial–mesenchymal plasticity, cytoskeletal remodeling, and context-dependent MAPK/PI3K signaling outputs. Dysregulated KLF17 expression has been associated with altered invasive phenotypes and metastatic competency in multiple tumor models, making it a relevant node for mechanistic studies of progression and cellular state transitions. In human cells, KLF17 activity is commonly interrogated in relation to transcriptional repression/activation circuitry and the regulation of downstream EMT-associated targets.
KLF17 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous KLF17 expression without altering the underlying DNA sequence.
KLF17 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the KLF17 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 KLF17 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous KLF17 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native KLF17 locus and enabling the study of KLF17-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of KLF17 pathway restoration in tumor cells with silenced or reduced KLF17 expression.
