    Summary
    Predicted to enable branched-chain-amino-acid transaminase activity. Predicted to be involved in L-leucine biosynthetic process and L-valine biosynthetic process. Predicted to act upstream of or within amino acid biosynthetic process; branched-chain amino acid biosynthetic process; and lipid metabolic process. Predicted to be active in mitochondrion. Is expressed in liver and muscle. Human ortholog(s) of this gene implicated in hypervalinemia and hyperleucine-isoleucinemia. Orthologous to human BCAT2 (branched chain amino acid transaminase 2).

    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.
