Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Inhibits pyruvate dehydrogenase activity by phosphorylation of the E1 subunit PDHA1, and thereby regulates glucose metabolism and aerobic respiration. Can also phosphorylate PDHA2. Decreases glucose utilization and increases fat metabolism in response to prolonged fasting, and as adaptation to a high-fat diet. Plays a role in glucose homeostasis and in maintaining normal blood glucose levels in function of nutrient levels and under starvation. Plays a role in the generation of reactive oxygen species.CATALYTIC ACTIVITY L-seryl-[pyruvate dehydrogenase E1 alpha subunit] + ATP = O-phospho-L-seryl-[pyruvate dehydrogenase E1 alpha subunit] + ADP + H(+)ACTIVITY REGULATION Activated by interaction with DLAT. Inhibited by AZD7545, dichloroacetate and radicicol.SUBUNIT Homodimer. Interacts with the pyruvate dehydrogenase complex subunit DLAT, and is part of the multimeric pyruvate dehydrogenase complex that contains multiple copies of pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (DLAT, E2) and lipoamide dehydrogenase (DLD, E3).INTERACTION Expressed in heart, skeletal muscle, spinal cord, as well as fetal and adult brain.INDUCTION Up-regulated in response to hypoxia. Up-regulated in response to fatty acids. Up-regulated by PPARD.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the PDK/BCKDK protein kinase family.
