Rabbit anti-Human PDK2 Polyclonal Antibody

Uniprot Id

Q15119

Target Species

Human

Target Name

PDK2

Target Full Name

[Pyruvate dehydrogenase (acetyl-transferring)] kinase isozyme 2, mitochondrial

Target Function

Kinase that plays a key role in the 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. Mediates cellular responses to insulin. Plays an important role in maintaining normal blood glucose levels and in metabolic adaptation to nutrient availability. 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. Plays a role in the regulation of cell proliferation and in resistance to apoptosis under oxidative stress. Plays a role in p53/TP53-mediated apoptosis.

Target Subcellular Location

Mitochondrion matrix.

Target Protein Families

PDK/BCKDK protein kinase family

Target Tissue Specificity

Expressed in many tissues, with the highest level in heart and skeletal muscle, intermediate levels in brain, kidney, pancreas and liver, and low levels in placenta and lung.

Target Synonyms

[Pyruvate dehydrogenase [lipoamide]] kinase isozyme 2; mitochondrial; PDHK2; PDK2; PDK2_HUMAN; Pyruvate dehydrogenase kinase isoform 2; Pyruvate dehydrogenase kinase, isozyme 2; Pyruvate dehydrogenase lipoamide kinase isozyme 2, mitochondrial

Target Background

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.
