PDHA1, pyruvate dehydrogenase E1 subunit alpha 1, is a major mitochondrial component of pyruvate dehydrogenase complexes (PDCs) which catalyzes oxidative decarboxylation of pyruvate in glycolysis and produces acetyl-CoA for the tricarboxylic acid (TCA) cycle. PDHA1 and PDHB form the heteroterameric pyruvate dehydrogenase E1 (E1) subunit of the PDC. The enzymatic activity of the PDC is regulated by phosphorylation of PDHA1 through pyruvate dehydrogenase kinase (PDK) and pyruvate dehydrogenase phosphatases (PDP). PDCs play crucial physiological functions between fed and fasting states which regulate pyruvate metabolism to maintain glucose homeostasis. PDHA1 enzymatic dysfunction causes fatal lactic acidosis and chronic neurologic dysfunction in the central nervous system. The decreased expression of PDHA1 in Parkinson’s disease and dementia with Lewy bodies patients suggests a dysfunction of mitochondrial energy production. Additionally, dysregulation of PDHA1 is found in multiple cancers, including lung, ovarian, stomach, and kidney, suggesting a role for PDHA1 in tumorigenesis.
