IKKβ promotes metabolic adaptation to glutamine deprivation via phosphorylation and inhibition of PFKFB3.We demonstrate that IKKβ directly interacts with and phosphorylates 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase isoform 3 (PFKFB3), a major driver of aerobic glycolysis, at Ser269 upon glutamine deprivation to inhibit its activity, thereby down-regulating aerobic glycolysis when glutamine levels are low. |

We also found that AMP activated protein kinase and protein kinases A, B, and C catalyzed the phosphorylation of Ser-460 of HBP1, and that in addition both isoforms are phosphorylated at a second, as yet undetermined site by protein kinase C. However, none of the phosphorylations had any effect on the intrinsic kinetic characteristics of either enzymatic activity, and neither did point mutation (mimicking phosphorylation), deletion, and alternative-splice modification of the HBP1 carboxy-terminal region. Instead, these phosphorylations and mutations decreased the sensitivity of the 6PF2K to a potent allosteric inhibitor, phosphoenolpyruvate, which appears to be the major regulatory mechanism. |

PFKFB3, is highly induced by hypoxia and the hypoxia mimics cobalt and desferrioxamine. This induction could be replicated by the use of an inhibitor of the prolyl hydroxylase enzymes responsible for the von Hippel Lindau (VHL)-dependent destabilization and tagging of HIF-1α. The absolute dependence of the PFKFB3 gene on HIF-1 was confirmed by its overexpression in VHL-deficient cells and by the lack of hypoxic induction in mouse embryonic fibroblasts conditionally nullizygous for HIF-1α |
