UniProt Comment
  • Kinase that plays a key role in regulation of glucose and fatty acid metabolism and homeostasis via phosphorylation of the pyruvate dehydrogenase subunits PDHA1 and PDHA2. This inhibits pyruvate dehydrogenase activity, and thereby regulates metabolite flux through the tricarboxylic acid cycle, down-regulates aerobic respiration and inhibits the formation of acetyl-coenzyme A from pyruvate. Plays an important role in cellular responses to hypoxia and is important for cell proliferation under hypoxia. Protects cells against apoptosis in response to hypoxia and oxidative stress.
Targeted by drugs (based on IPA annotation)
  • dichloroacetic acid
Wiki Pathways
  • DNA damage response (only ATM dependent)
  • EPO Receptor Signaling
  • ErbB signaling pathway
  • TCA Cycle

  • Signaling by Retinoic Acid

All locus annotations are based on the sentinel SNP (rs12052479) and 17 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
