Glucose-6-phosphate isomerase (GPI) is a cytosolic enzyme that catalyzes the reversible interconversion of glucose-6-phosphate and fructose-6-phosphate, linking glycolysis and gluconeogenesis and influencing cellular energy balance. By shaping carbon flux through central metabolism, GPI can affect redox homeostasis and biosynthetic precursor availability in proliferative and stress-adapted cells. Beyond its canonical enzymatic role, GPI has been implicated in extracellular signaling activities that can modulate cell motility and microenvironmental interactions, depending on context. Genetic or functional perturbation of GPI is associated with metabolic dysregulation and has been studied in relation to anemia and neurodevelopmental phenotypes as well as metabolic features observed in cancer models.
GPI Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GPI locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GPI. 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 GPI 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 GPI-disrupted clones.
