Pyruvate dehydrogenase kinase, isozyme 2

PDK2, pyruvate dehydrogenase kinase 2, pyruvate dehydrogenase kinase isoform 2, PDHK2
This gene encodes a member of the pyruvate dehydrogenase kinase family. The encoded protein phosphorylates pyruvate dehydrogenase, down-regulating the activity of the mitochondrial pyruvate dehydrogenase complex. Overexpression of this gene may play a role in both cancer and diabetes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Pyruvate dehydrogenase kinase isoform 2 (PDK2) was identified as a key regulatory protein, and its activation proved necessary for relevant myointima formation.
Regulation of glycolysis by Pdk functions as a metabolic checkpoint for cell cycle quiescence in hematopoietic stem cells.
Suda et al., Tokyo, Japan. In Cell Stem Cell, 2013
Here we directly investigated this idea using metabolomic analysis and found that HSCs generate adenosine-5'-triphosphate by anaerobic glycolysis through a pyruvate dehydrogenase kinase (Pdk)-dependent mechanism.
p53 negatively regulates transcription of the pyruvate dehydrogenase kinase Pdk2.
Harris et al., New Brunswick, United States. In Cancer Res, 2012
Results established that wild-type p53 prevents manifestation of the Warburg effect by controlling Pdk2. These findings elucidate a new mechanism by which p53 suppresses tumorigenesis acting at the level of cancer cell metabolism.
