Specification

• Species: Human
• Source: E.coli
• Tag: His
• ProteinLength: 2-520 a.a.
• Description: 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) is involved in both the synthesis and degradation of fructose-2,6-bisphosphate, a regulatory molecule that controls the activity of the enzymes phosphofructokinase 1 (PFK-1) and fructose 1,6-bisphosphatase (FBPase-1) to regulate glycolysis and gluconeogenesis. PFKFB3 has a 6-phosphofructo-2-kinase activity that catalyzes the synthesis of fructose-2,6-bisphosphate, and a fructose-2,6-biphosphatase activity that catalyzes the degradation of fructose-2,6-bisphosphate. Recently, it is reported to be involved in vessel sprouting of endothelial cells (ECs). ECs rely on glycolysis rather than on oxidative phosphorylation for ATP production and that loss of the glycolytic activator PFKFB3 in ECs impairs vessel formation. PFKFB3 also plays a crucial role in the progression of cancerous cells by enabling their glycolytic pathways even under severe hypoxic conditions, which makes it a potential target for cancer therapy. The kinase activity of recombinant human PFKFB3 was assayed using a phosphatase-coupled method.
