    basic FUNCTION
  • phosphorylating PDH and resulting in its inactivation and thus contributing to the regulation of glucose metabolism
  • plays an important role in maintaining glycolysis
  • activates a group of kinases, including AKT1, p70 ribosomal S6 kinase (S6K), and serum and glucocorticoid-induced protein kinase (SGK), that mediate many of the effects of insulin as well as other agonists
  • BNIP3 and PDK1 are involved in two important pathways, cell death and glycolytic, playing critical roles in these pathways in cardiomyocytes after severe hypoxia
  • plays an indispensable role in the development of the cardiovascular system
  • important regulator of PDH in clonal beta-cells and PDK1 and PDH are important for efficient metabolic coupling
  • PDK1 and PDK2 promote meiotic maturation, as their knockdown disturbs the assembly of the meiotic apparatus, without significantly altering ATP content
  • CELLULAR PROCESS protein, post translation

    REGULATION
    Other regulated by HIF1A (HIF regulation has a key role in maintaining lactate production in human cancer)
    regulation by HIF1A (HIF-1-mediated expression of PDK1: a metabolic switch required for cellular adaptation to hypoxia)
    tyrosine phosphorylation enhances PDK1 kinase activity by promoting ATP and pyruvate dehydrogenase complex binding
