Biochem/physiol Actions

Recombinant full-length human PFKFB3 was expressed by Baculovirus in Sf9 insect cells using an N-terminal GST tag. PFKFB3 or 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 is a potent activator of a key regulatory enzyme in the glycolysis pathway called phosphofructokinase. Phosphofructokinase regulates the steady-state concentration of fructose-2,6-bisphosphate, a potent activator of key regulatory enzyme of the glycolysis pathway. PFKFB3 is bifunctional, although the phosphatase activity is low due to a mutation in an active site which can be upregulated after phosphorylation by protein kinases ⁽¹⁾. PFKFB3 may be responsible for sustaining the high glycolytic flux of rapidly proliferating leukemia cells and may represent a molecular target for chemotherapeutic intervention ⁽²⁾.
