GRIN1 encodes the NMDA receptor subunit NMDAζ1 (also known as GluN1), an essential component of heterotetrameric ionotropic glutamate receptors that mediate Ca²⁺-permeable excitatory neurotransmission in the human central nervous system. NMDAζ1-containing receptors integrate synaptic activity with downstream signaling pathways that regulate synaptic plasticity, neuronal development, and activity-dependent gene expression, including CaMK/CREB- and MAPK-associated processes. GRIN1 function is tightly coupled to excitatory/inhibitory balance, long-term potentiation, and network maturation, making it a key node in pathways governing learning and memory. Dysregulated NMDA receptor signaling and GRIN1 variation have been linked to neurodevelopmental and neuropsychiatric phenotypes, motivating mechanistic studies of receptor composition and transcriptional control.
NMDAζ1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GRIN1 expression without altering the underlying DNA sequence.
NMDAζ1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GRIN1 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 GRIN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NMDAζ1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GRIN1 locus and enabling the study of NMDAζ1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NMDAζ1 pathway restoration in tumor cells with silenced or reduced GRIN1 expression.
