NPAT CRISPR Activation Plasmid (h) | sc-404086-ACT | 20 µg | $397.00 |
Human NPAT encodes a nuclear protein that functions as a transcriptional regulator tightly coupled to cell cycle progression. NPAT is a key component of the histone gene transcription program, coordinating S phase–dependent expression of replication-dependent histone genes and supporting chromatin assembly during DNA replication. Through its association with nuclear substructures and phosphorylation by cyclin-dependent kinases, NPAT integrates checkpoint and proliferation signals that influence genome stability. Dysregulated NPAT activity and altered histone gene control have been linked to aberrant proliferation phenotypes, making NPAT relevant for studies of oncogenic cell cycle control and chromatin-driven disease mechanisms.
NPAT CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous NPAT expression without altering the underlying DNA sequence.
NPAT CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the NPAT 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 NPAT transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NPAT expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native NPAT locus and enabling the study of NPAT-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NPAT pathway restoration in tumor cells with silenced or reduced NPAT expression.
