Biological Information

Background Information:

PDHK1 (pyruvate dehydrogenase kinase 1) is a mitochondrial enzyme that regulates cellular metabolism by inhibiting the pyruvate dehydrogenase (PDH) complex. It phosphorylates and inactivates PDH, controlling pyruvate entry into the TCA cycle and balancing glycolysis and oxidative phosphorylation. Regulated by hormones, nutrients, and oxygen levels, PDHK1 is crucial for glucose homeostasis, energy production, and metabolic adaptation. As a key metabolic regulator, it's a potential therapeutic target for metabolic disorders, cancer, and other diseases characterized by aberrant cellular metabolism. PDHK1 enhancement may protect cognitive recovery, while its inhibition is associated with various disorders, including abnormal myelination, hypoglycemia, ketoacidosis, seizures, and peripheral neuropathy.

Testing Information

Procedure Summary:

Human recombinant protein kinase PDHK1 expressed in Sf9 insect cells is used. Test compound and/or vehicle is preincubated with 4 μg/ml enzyme in modified Tris-HCl buffer pH 7.4 for 15 minutes at 37˚C. The reaction is initiated by addition of 200 μg/ml PDHKtide and 10 μM ATP for another 90- minute incubation period and terminated by ADP-GloTM Reagent. Read luminescence on a spectrophotometer after adding Kinase Detection Regent. Compounds are screened at 10 μM.
