NEDD4-L CRISPR Activation Plasmid (h) | sc-403647-ACT | 20 µg | $397.00 |
NEDD4L encodes NEDD4-L, a HECT-type E3 ubiquitin ligase that regulates protein turnover by catalyzing ubiquitin transfer to specific membrane and cytosolic substrates. It is best known for controlling epithelial sodium channel (ENaC) surface abundance and trafficking, linking NEDD4-L activity to ion transport, fluid homeostasis, and cellular stress responses. NEDD4-L also intersects with signaling pathways including TGF-β/SMAD and Wnt/β-catenin through ubiquitin-dependent modulation of pathway components, influencing cell differentiation and tissue remodeling. Altered NEDD4L expression or function has been associated with dysregulated sodium handling and aberrant signaling programs implicated in cardiometabolic and fibrotic disease biology.
NEDD4-L CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous NEDD4L expression without altering the underlying DNA sequence.
NEDD4-L CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the NEDD4L 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 NEDD4L transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NEDD4-L expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native NEDD4L locus and enabling the study of NEDD4-L-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NEDD4-L pathway restoration in tumor cells with silenced or reduced NEDD4L expression.
