GABRG2 encodes the γ2 subunit of the human GABA\_A receptor, a ligand-gated chloride channel that mediates fast inhibitory synaptic transmission in the central nervous system. Incorporation of γ2 influences receptor assembly, synaptic clustering via gephyrin, and pharmacological sensitivity, shaping neuronal excitability and network oscillations. GABA\_A receptor signaling intersects with activity-dependent synaptic plasticity pathways and excitation–inhibition balance programs critical for circuit development and homeostasis. Genetic and functional perturbation of GABRG2 has been linked to neurodevelopmental and seizure-related phenotypes, supporting its relevance for mechanistic studies of inhibitory neurotransmission.
GABAA Rγ2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GABRG2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GABRG2. 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 GABRG2 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 GABRG2-disrupted clones.
