Summaries for PDHA2 Gene

GeneCards Summary for PDHA2 Gene

PDHA2 (Pyruvate Dehydrogenase E1 Alpha 2 Subunit) is a Protein Coding gene. Diseases associated with PDHA2 include Spermatogenic Failure 1. Among its related pathways are Pyruvate metabolism and Carbon metabolism. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on the aldehyde or oxo group of donors, disulfide as acceptor and pyruvate dehydrogenase (acetyl-transferring) activity. An important paralog of this gene is PDHA1.

UniProtKB/Swiss-Prot Summary for PDHA2 Gene

  • The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the glycolytic pathway to the tricarboxylic cycle.

    Quaternary structure:
    • Heterotetramer of two PDHA2 and two PDHB subunits. The heterotetramer interacts with 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). These subunits are bound to an inner core composed of about 48 DLAT and 12 PDHX molecules.

Selected DME Specific Peptides for PDHA2 Gene


Post-translational modifications for PDHA2 Gene

  • Phosphorylation at Ser-205, Ser-266 and Ser-273 by PDK family kinases inactivates the enzyme; for this phosphorylation at a single site is sufficient. Phosphorylation at Ser-266 interferes with access to active site, and thereby inactivates the enzyme. Dephosphorylation at all three sites, i.e. at Ser-205, Ser-266 and Ser-273, is required for reactivation.
