| 736556 | PDHA1 | pyruvate dehydrogenase E1 subunit alpha 1 | The pyruvate dehydrogenase (PDH) complex is a nuclear-encoded mitochondrial multienzyme complex that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2), and provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle. The PDH complex is composed of multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3). The E1 enzyme is a heterotetramer of two alpha and two beta subunits. This gene encodes the E1 alpha 1 subunit containing the E1 active site, and plays a key role in the function of the PDH complex. Mutations in this gene are associated with pyruvate dehydrogenase E1-alpha deficiency and X-linked Leigh syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2010] | X | 19343927 | 19361718 | Human | 452 | symbol , COSMIC , Human Proteome Map | gene, protein-coding, REVIEWED [RefSeq] |
| 736557 | Pdha1 | pyruvate dehydrogenase E1 alpha 1 | Enables pyruvate dehydrogenase (NAD+) activity. Acts upstream of or within pyruvate decarboxylation to acetyl-CoA. Located in mitochondrion. Part of catalytic complex. Is expressed in several structures, including alimentary system; brain; heart ventricle; metanephros; and sensory organ. Human ortho log(s) of this gene implicated in pyruvate decarboxylase deficiency. Orthologous to human PDHA1 (pyruvate dehydrogenase E1 subunit alpha 1).
