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

ANIMAL & CELL MODELS

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