Carbonic anhydrase VIII (CA VIII), encoded by the human CA8 gene, is an acatalytic member of the carbonic anhydrase family that modulates intracellular signaling rather than CO₂ hydration. CA VIII binds and inhibits inositol 1,4,5-trisphosphate receptor type 1 (ITPR1), shaping IP₃-dependent Ca²⁺ release from the endoplasmic reticulum and thereby influencing neuronal excitability, synaptic plasticity, and cerebellar motor coordination. Through its impact on Ca²⁺-regulated pathways, including CaMK and calcineurin-dependent transcriptional programs, CA8 contributes to homeostatic control of calcium signaling. Genetic disruption or dysregulation of CA8 has been linked to cerebellar dysfunction and ataxia-related neurobiology, making it a useful target for mechanistic studies of calcium signaling in neural systems.
CA VIII Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CA8 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CA8. 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 CA8 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 CA8-disrupted clones.
