NSE1 CRISPR Activation Plasmid (h) | sc-402593-ACT | 20 µg | $397.00 |
Human NSMCE1 encodes NSE1, a core component of the SMC5/6 complex that safeguards genome integrity during DNA replication and repair. NSE1 contains a RING-type E3 ubiquitin ligase activity and cooperates with other SMC5/6 subunits to coordinate replication fork stability, homologous recombination, and resolution of DNA damage–associated recombination intermediates. Through these pathways, NSE1 contributes to chromosome segregation and suppression of deleterious genome rearrangements under replicative stress. Dysregulation of SMC5/6 complex function is linked to genome instability phenotypes relevant to studies of cancer biology, chromosomal breakage, and DNA repair disorders.
NSE1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous NSMCE1 expression without altering the underlying DNA sequence.
NSE1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the NSMCE1 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 NSMCE1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NSE1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native NSMCE1 locus and enabling the study of NSE1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NSE1 pathway restoration in tumor cells with silenced or reduced NSMCE1 expression.
