FZD1 encodes frizzled-1, a seven-transmembrane WNT receptor that couples extracellular WNT ligands to intracellular signaling cascades controlling cell fate specification, polarity, and proliferation. Upon ligand binding, frizzled-1 can activate canonical β-catenin/TCF transcriptional programs and intersect with non-canonical planar cell polarity and WNT/Ca²⁺ pathways, influencing cytoskeletal dynamics and migration. Dysregulated FZD1 signaling has been linked to aberrant WNT network activity observed in oncogenic transformation, fibrosis, and developmental disorders. As a cell-surface receptor, frizzled-1 is also useful for studying ligand–receptor selectivity, pathway cross-talk, and receptor trafficking in human model systems.
frizzled-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous FZD1 expression without altering the underlying DNA sequence.
frizzled-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the FZD1 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 FZD1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous frizzled-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native FZD1 locus and enabling the study of frizzled-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of frizzled-1 pathway restoration in tumor cells with silenced or reduced FZD1 expression.
