HOMOLOGY

FAMILY
  • phosphofructokinase family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytosolic
    basic FUNCTION
  • rate-limiting enzyme in glycolysis
  • muscle isoform of phosphofructokinase (PFK), which phosphorylates fructose-6-phosphate to fructose-1,6-bisphosphate, commiting glucose to glycolysis (Garcia 2009)
  • glycolytic efficiency, which is important for the survival of cancer cells, depends primarily on the preferential expression of PFKL over the PFKM and PFKP isoforms
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS coagulation/hemostasis
    PATHWAY
    metabolism energetic , monocarbon
    signaling
  • fructose metabolism
  • energy pathway
  • glucose metabolism
  • glycogen metabolism

    ANIMAL & CELL MODELS
    Pfkm(-/-) mice had high lethality around weaning and reduced lifespan, because of the metabolic alterations (Garcia 2009)
