CC -!- FUNCTION: Required for anchoring dihydrolipoamide dehydrogenase (E3) to
CC the dihydrolipoamide transacetylase (E2) core of the pyruvate
CC dehydrogenase complexes of eukaryotes. This specific binding is
CC essential for a functional PDH complex.
CC -!- SUBUNIT: Part of the inner core of the multimeric pyruvate
CC dehydrogenase complex that is composed of about 48 DLAT and 12 PDHX
CC molecules (PubMed:14638692, PubMed:20361979). This core binds multiple
CC copies of pyruvate dehydrogenase (subunits PDH1A and PDHB, E1),
CC dihydrolipoamide acetyltransferase (DLAT, E2) and lipoamide
CC dehydrogenase (DLD, E3) (PubMed:14638692). Interacts with SIRT4
CC (PubMed:25525879). Interacts with DLD (PubMed:20385101,
CC PubMed:16263718, PubMed:16442803, PubMed:20160912, PubMed:20361979).

CC complex activity. {ECO:0000269|PubMed:25525879}.
CC -!- DISEASE: Pyruvate dehydrogenase E3-binding protein deficiency (PDHXD)
CC [MIM:245349]: A metabolic disorder characterized by decreased activity
CC of the pyruvate dehydrogenase complex without observable reduction in
CC the activities of enzymes E1, E2, or E3. Clinical features include
CC hypotonia and psychomotor retardation. {ECO:0000269|PubMed:9399911}.
CC Note=The disease is caused by variants affecting the gene represented
CC in this entry.
CC -!- SIMILARITY: Belongs to the 2-oxoacid dehydrogenase family.
