GRIK1 encodes the kainate-type ionotropic glutamate receptor subunit GluR-5 (GluK1), a ligand-gated cation channel that contributes to fast excitatory neurotransmission in the central and peripheral nervous systems. GluR-5 participates in synaptic signaling and plasticity by modulating membrane depolarization and downstream Ca2+-dependent pathways, influencing neuronal excitability and circuit dynamics. Through its role in glutamatergic signaling networks, altered GRIK1/GluR-5 activity has been associated with neuropsychiatric and neurological phenotypes, including seizure susceptibility and dysregulated excitatory–inhibitory balance. These features make GRIK1 a useful target for mechanistic studies of receptor biology, synaptic function, and activity-dependent transcriptional responses.
GluR-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GRIK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GRIK1. 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 GRIK1 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 GRIK1-disrupted clones.
