Nolz-1 CRISPR Activation Plasmid (h) | sc-405058-ACT | 20 µg | $397.00 |
Human ZNF503 encodes the zinc finger transcription factor Nolz-1, a nuclear regulator that shapes gene expression programs governing cell fate specification, differentiation, and tissue patterning. Nolz-1 activity is commonly studied in the context of transcriptional repression/activation networks and developmental signaling crosstalk that influence lineage commitment and morphogenesis. Dysregulated expression of ZNF503 has been associated with altered differentiation states and proliferative phenotypes in multiple disease research settings, including cancer biology and neurodevelopmental models. As a DNA-binding regulator, Nolz-1 provides a tractable node for dissecting upstream regulatory inputs and downstream transcriptional targets that control cellular identity.
Nolz-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ZNF503 expression without altering the underlying DNA sequence.
Nolz-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ZNF503 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 ZNF503 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Nolz-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ZNF503 locus and enabling the study of Nolz-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Nolz-1 pathway restoration in tumor cells with silenced or reduced ZNF503 expression.
