Pyruvate dehydrogenase kinase, isozyme 1, also known as PDK1, is a human gene.[1] It codes for an isozyme of pyruvate dehydrogenase kinase (PDK).

Pyruvate dehydrogenase (PDH) is a part of 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.[1]
