PDHA2 (Pyruvate Dehydrogenase E1 Alpha 2 Subunit) is a Protein Coding gene. Among its related pathways are Glucagon signaling pathway and Glucose metabolism. PDHA2 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 PDHA2 is PDHA1.
