ITPR2 encodes the inositol 1,4,5-trisphosphate receptor type 2 (IP3R-II), an endoplasmic reticulum Ca²⁺ release channel that converts phospholipase C–derived IP₃ signals into cytosolic calcium transients. IP3R-II–mediated Ca²⁺ flux regulates excitation–secretion coupling, epithelial and endothelial signaling, and transcriptional programs through pathways such as CaMK, calcineurin/NFAT, and mitochondrial Ca²⁺ crosstalk. Through spatially restricted Ca²⁺ waves, IP3R-II influences cell metabolism, apoptosis susceptibility, and barrier or transport functions in specialized tissues. Altered ITPR2 activity or expression has been associated with dysregulated Ca²⁺ homeostasis in conditions affecting secretory epithelia and related physiological processes, supporting its use in mechanistic studies of calcium signaling networks.
IP3R-II Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ITPR2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ITPR2. 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 ITPR2 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 ITPR2-disrupted clones.
