KCNJ6 encodes the human inwardly rectifying potassium channel KIR3.2 (GIRK2), a G protein–gated ion channel that couples GPCR signaling to membrane hyperpolarization and reduced cellular excitability. KIR3.2 contributes to potassium conductance in neurons and other excitable tissues, integrating neurotransmitter and neuromodulator inputs through Gβγ-mediated gating and shaping firing patterns, synaptic transmission, and network activity. This channel participates in pathways linking GPCR activation to ion homeostasis and electrophysiological control, with downstream effects on calcium entry and activity-dependent signaling. Dysregulation or genetic variation in KCNJ6 has been associated with neurophysiological and neurodevelopmental phenotypes, supporting its relevance in studies of excitability-driven disease mechanisms.
KIR3.2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the KCNJ6 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within KCNJ6. 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 KCNJ6 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 KCNJ6-disrupted clones.
