Cytokeratin 14 CRISPR Activation Plasmid (h) | sc-400362-ACT | 20 µg | $397.00 |
KRT14 encodes cytokeratin 14, a type I intermediate filament protein that heterodimerizes with keratin 5 to form the basal keratin network in stratified epithelia. This cytoskeletal scaffold supports mechanical resilience, cell–cell adhesion, and epithelial differentiation, and it interfaces with signaling nodes such as integrin/hemidesmosome complexes and cytoskeleton-regulated stress responses. Altered KRT14 expression or function is linked to epidermal fragility phenotypes and dysregulated keratinization, and it is frequently used as a marker of basal-like epithelial states in skin and glandular tissues. In cancer biology and tissue remodeling models, KRT14-associated programs are studied in relation to epithelial plasticity, invasion-associated phenotypes, and microenvironmental stress adaptation.
Cytokeratin 14 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous KRT14 expression without altering the underlying DNA sequence.
Cytokeratin 14 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the KRT14 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 KRT14 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Cytokeratin 14 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native KRT14 locus and enabling the study of Cytokeratin 14-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Cytokeratin 14 pathway restoration in tumor cells with silenced or reduced KRT14 expression.
