Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h): sc-404780-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h) and Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the CHRNE transcriptional start site. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Nicotinic Acetylcholine Receptor epsilon/CHRNE Antibody (B-11): sc-376747

CHRNE encodes the epsilon subunit of the muscle-type nicotinic acetylcholine receptor (nAChR), a ligand-gated ion channel that assembles at the postsynaptic membrane of the neuromuscular junction to mediate rapid synaptic transmission. Upon acetylcholine binding, the receptor opens to allow cation influx, coupling neurotransmitter signaling to membrane depolarization and excitation–contraction processes. CHRNE expression is developmentally regulated and contributes to receptor composition, localization, and channel kinetics in mature skeletal muscle. Genetic perturbations of CHRNE and other nAChR components are associated with congenital myasthenic syndromes, making it a key locus for studying neuromuscular signaling, synapse maintenance, and receptor assembly pathways.
Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CHRNE expression without altering the underlying DNA sequence.
Nicotinic Acetylcholine Receptor epsilon/CHRNE CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CHRNE 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 CHRNE transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Nicotinic Acetylcholine Receptor epsilon/CHRNE expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CHRNE locus and enabling the study of Nicotinic Acetylcholine Receptor epsilon/CHRNE-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Nicotinic Acetylcholine Receptor epsilon/CHRNE pathway restoration in tumor cells with silenced or reduced CHRNE expression.
