Negr1 encodes neuronal growth regulator 1 (NEGR1), a GPI-anchored IgLON family cell-adhesion molecule enriched at the neuronal surface where it supports neurite outgrowth, synaptic organization, and circuit maturation. In mouse nervous system models, NEGR1 is linked to activity-dependent connectivity and membrane microdomain signaling that influences axon guidance and spine dynamics. Altered NEGR1 expression has been associated with neurodevelopmental and neuropsychiatric phenotypes, and genetic studies have connected NEGR1 loci to body-weight regulation and behavioral traits. These features make NEGR1 a useful node for studying adhesion-mediated signaling, structural plasticity, and genotype–phenotype relationships in brain and metabolic research contexts.
NEGR1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Negr1 expression without altering the underlying DNA sequence.
NEGR1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Negr1 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 Negr1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NEGR1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Negr1 locus and enabling the study of NEGR1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NEGR1 pathway restoration in tumor cells with silenced or reduced Negr1 expression.
