Human PFKM encodes the muscle isoform of phosphofructokinase-1 (PFK-1), a rate-limiting glycolytic enzyme that converts fructose-6-phosphate to fructose-1,6-bisphosphate and helps control cellular ATP production. PFK-1 integrates metabolic cues through allosteric regulation by ATP, AMP, citrate, and fructose-2,6-bisphosphate, linking glycolytic flux to energy charge and biosynthetic demand. PFKM activity influences central carbon metabolism, lactate production, and redox balance, with downstream effects on stress responses and cell proliferation. Genetic disruption or altered regulation of PFKM is relevant to inborn errors of carbohydrate metabolism and broader metabolic remodeling observed in neuromuscular and proliferative phenotypes.
PFK-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PFKM locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PFKM. 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 PFKM 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 PFKM-disrupted clones.
