GRIA2 encodes the GluR-2 (GluA2) subunit of AMPA-type ionotropic glutamate receptors, a central determinant of fast excitatory synaptic transmission in the human brain. Incorporation and RNA editing of GluR-2 at the Q/R site regulate calcium permeability, channel conductance, and activity-dependent synaptic plasticity. GRIA2 participates in glutamatergic signaling pathways that shape neuronal development, learning, and circuit excitability through receptor trafficking and postsynaptic density organization. Dysregulation of GRIA2 expression or editing has been associated with altered excitatory–inhibitory balance and is studied in the context of neurodevelopmental and neurodegenerative disease mechanisms.
GluR-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GRIA2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GRIA2. 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 GRIA2 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 GRIA2-disrupted clones.
