PDK1 Rabbit Polyclonal Antibody

Pyruvate dehydrogenase (PDH) is a mitochondrial multienzyme complex that catalyzes the oxidative decarboxylation of pyruvate and is one of the major enzymes responsible for the regulation of homeostasis of carbohydrate fuels in mammals. The enzymatic activity is regulated by a phosphorylation/dephosphorylation cycle. Phosphorylation of PDH by a specific pyruvate dehydrogenase kinase (PDK) results in inactivation. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2013], catalytic activity:ATP + [pyruvate dehydrogenase (acetyl-transferring) ] = ADP + [pyruvate dehydrogenase (acetyl-transferring) ] phosphate., function:Inhibits the mitochondrial pyruvate dehydrogenase complex by phosphorylation of the E1 alpha subunit, thus contributing to the regulation of glucose metabolism., similarity:Belongs to the PDK/BCKDK protein kinase family., similarity:Contains 1 histidine kinase domain., tissue specificity:Expressed predominantly in the heart.
