Mouse Gria1 encodes the AMPA-type glutamate receptor subunit GluR-1 (GluA1), a core determinant of fast excitatory synaptic transmission in the central nervous system. GluR-1-containing receptors regulate synaptic strength through activity-dependent trafficking and phosphorylation, supporting long-term potentiation and other forms of synaptic plasticity. This signaling intersects with Ca2+-dependent cascades including CaMKII/PKA/PKC and downstream transcriptional programs that shape neuronal excitability and circuit remodeling. Dysregulated AMPAR function and altered GRIA1 expression have been linked to neurodevelopmental and neuropsychiatric phenotypes as well as seizure susceptibility, making Gria1 a key target for mechanistic studies of glutamatergic neurotransmission.
GluR-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Gria1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Gria1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Gria1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Gria1-disrupted clones.
