Net CRISPR Activation Plasmid (h) | sc-405945-ACT | 20 µg | $397.00 |
ELK3 (Net) is an ETS-domain transcription factor that functions predominantly as a transcriptional repressor and context-dependent activator downstream of RAS–RAF–MEK–ERK signaling. By forming ternary complexes with serum response factor at serum response elements, Net integrates mitogen and stress cues to regulate immediate-early gene programs, cytoskeletal remodeling, and cell-state transitions. Net activity influences processes such as endothelial biology, migration, and invasion through regulation of target genes linked to MAPK-driven transcriptional outputs. Dysregulated ELK3 expression or signaling has been associated with oncogenic programs, angiogenesis-related phenotypes, and metastatic potential, making it a relevant node for mechanistic studies of tumor progression and vascular remodeling.
Net CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ELK3 expression without altering the underlying DNA sequence.
Net CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ELK3 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 ELK3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Net expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ELK3 locus and enabling the study of Net-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Net pathway restoration in tumor cells with silenced or reduced ELK3 expression.
