    Summary
    Predicted to enable acetyltransferase activity; lipoic acid binding activity; and ubiquitin protein ligase binding activity. Predicted to contribute to branched-chain alpha-keto acid dehydrogenase activity. Predicted to be involved in branched-chain amino acid catabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; central nervous system; integumental system; sensory organ; and urinary system. Used to study maple syrup urine disease. Human ortholog(s) of this gene implicated in maple syrup urine disease. Orthologous to human DBT (dihydrolipoamide branched chain transacylase E2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
