Human ME1 encodes cytosolic NADP-dependent malic enzyme 1, which catalyzes the oxidative decarboxylation of malate to pyruvate while generating NADPH. This activity supports reductive biosynthesis and redox homeostasis by supplying NADPH for fatty acid and cholesterol synthesis and for antioxidant systems such as glutathione and thioredoxin. ME1 function integrates with central carbon metabolism, linking glycolysis, the tricarboxylic acid cycle, and anaplerotic fluxes that influence cellular energy balance. Dysregulated ME1 expression or activity has been associated with metabolic reprogramming in proliferative states and with altered lipid metabolism and oxidative stress phenotypes relevant to cancer and metabolic disease research.
ME1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ME1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ME1. 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 ME1 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 ME1-disrupted clones.
