KCNJ11 encodes the inwardly rectifying potassium channel subunit KIR6.2, a core component of ATP-sensitive K+ (KATP) channels that couple cellular metabolic state to membrane excitability. In pancreatic beta cells, KIR6.2 helps set resting potential and regulates glucose-stimulated insulin secretion by integrating ATP/ADP-dependent gating with changes in cytosolic Ca2+ entry. In excitable tissues such as heart and skeletal muscle, KATP channels modulate action potential duration and protect against metabolic stress through electrophysiological adaptation. Genetic variation or altered regulation of KCNJ11 has been associated with disorders of insulin secretion and glucose homeostasis, making it a widely used target in metabolic signaling and ion channel physiology research.
KIR6.2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the KCNJ11 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within KCNJ11. 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 KCNJ11 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 KCNJ11-disrupted clones.
