简介
The PFKFB3 protein is a key player in cellular energy metabolism as it exerts dual functions by catalyzing the synthesis and degradation of fructose 2,6-bisphosphate (F-2,6-BP). F-2,6-BP is an important allosteric regulator of glycolysis, controlling glucose utilization for energy production. PFKFB3 Protein, Human (His) is the recombinant human-derived PFKFB3 protein, expressed by E. coli , with N-6*His labeled tag.

Protein Description
PFKFB3, a member of the 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase family, plays a critical role in regulating glycolysis and gluconeogenesis by modulating the levels of fructose-2,6-bisphosphate, a potent allosteric activator of phosphofructokinase-1. The enzyme is intricately linked to cellular metabolism and energy homeostasis, making it a significant target for understanding metabolic disorders, including cancer and diabetes, where altered glycolytic pathways are often observed. Research has shown that PFKFB3 is upregulated in several cancers, contributing to the Warburg effect, where cancer cells preferentially utilize glycolysis for energy production, even in the presence of oxygen. This unique metabolic adaptation supports rapid cell proliferation and survival under hypoxic conditions. Consequently, the development of recombinant PFKFB3 proteins offers valuable insights into its structural and functional properties, enabling researchers to explore its potential as a therapeutic target. Studies utilizing recombinant PFKFB3 can elucidate its enzymatic mechanisms, interactome, and regulatory pathways, further illuminating its role in metabolic reprogramming within tumor microenvironments. Moreover, understanding the molecular basis of PFKFB3's function could lead to novel strategies for designing inhibitors, providing promising avenues for cancer treatment and management of metabolic diseases. Thus, the study of recombinant PFKFB3 not only enhances our understanding of fundamental metabolic processes but also opens doors for innovative therapeutic interventions.
