Gria2 encodes the AMPA-type glutamate receptor subunit GluR-2 (GluA2), a core determinant of fast excitatory synaptic transmission in the mouse central nervous system. RNA editing at the Q/R site and regulated trafficking of GluR-2 shape AMPAR Ca2+ permeability, channel conductance, and synaptic plasticity processes such as LTP/LTD. Through interactions with scaffolding proteins and phosphorylation-dependent signaling, GluR-2 contributes to activity-dependent receptor insertion and removal at postsynaptic membranes. Altered GRIA2 function or regulation is widely studied in the context of excitatory/inhibitory imbalance, synaptic remodeling, and mechanisms implicated in neurodegeneration, epilepsy, and neurodevelopmental phenotypes.
GluR-2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Gria2 locus in mouse 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.
