Human GRM2 encodes the metabotropic glutamate receptor mGluR-2, a class C GPCR that couples primarily to Gi/o proteins to suppress adenylyl cyclase activity and modulate downstream cAMP/PKA signaling. mGluR-2 functions as a key regulator of presynaptic neurotransmitter release and synaptic plasticity, shaping excitatory transmission through modulation of ion channels and neurotransmitter release machinery. Through these mechanisms, GRM2 participates in neuronal network homeostasis and activity-dependent signaling programs relevant to learning and stress responsiveness. Altered GRM2/mGluR-2 signaling has been linked to neuropsychiatric and neurodevelopmental phenotypes, supporting its use in mechanistic studies of glutamatergic circuit dysfunction.
mGluR-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GRM2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GRM2. 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 GRM2 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 GRM2-disrupted clones.
