PDK4 Antibody (E265)

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

  • WB - PDK4 Antibody (E265) AP7041C
    Western blot analysis of PDK4 Antibody (E265) in CEM cell line lysates (35ug/lane). PDK4 (arrow) was detected using the purified Pab.
  • IHC-P - PDK4 Antibody (E265) AP7041C
    Formalin-fixed and paraffin-embedded human skeletal muscle tissue reacted with PDK4-E265, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Name PDK4
Synonyms PDHK4
Function 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. Inhibition of pyruvate dehydrogenase decreases glucose utilization and increases fat metabolism in response to prolonged fasting and starvation. Plays an important role in maintaining normal blood glucose levels under starvation, and is involved in the insulin signaling cascade. Via its regulation of pyruvate dehydrogenase activity, plays an important role in maintaining normal blood pH and in preventing the accumulation of ketone bodies under starvation. In the fed state, mediates cellular responses to glucose levels and to a high-fat diet. Regulates both fatty acid oxidation and de novo fatty acid biosynthesis. Plays a role in the generation of reactive oxygen species. Protects detached epithelial cells against anoikis. Plays a role in cell proliferation via its role in regulating carbohydrate and fatty acid metabolism.
Cellular Location Mitochondrion matrix.
Tissue Location Ubiquitous; highest levels of expression in heart and skeletal muscle.
