NAT-11 CRISPR Activation Plasmid (h) | sc-413259-ACT | 20 µg | $397.00 |
Human NAA40 encodes the N-terminal acetyltransferase NAT-11, a GNAT-family enzyme best known for catalyzing Nα-acetylation of histone H4 at serine 1, a chromatin-associated modification that helps tune transcriptional programs. Through modulation of nucleosome function and epigenetic signaling, NAT-11 links acetyl-CoA–dependent acetylation chemistry to genome regulation, cell-cycle progression, and differentiation-related gene expression. Altered NAA40 activity or expression has been associated with dysregulated chromatin states observed in proliferative and stress-response contexts, making it relevant for studies of epigenetic control, transcriptional remodeling, and disease-associated gene expression signatures.
NAT-11 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous NAA40 expression without altering the underlying DNA sequence.
NAT-11 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the NAA40 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 NAA40 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NAT-11 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native NAA40 locus and enabling the study of NAT-11-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NAT-11 pathway restoration in tumor cells with silenced or reduced NAA40 expression.
