Summary: Enables branched-chain-amino-acid transaminase activity. Involved in branched-chain amino acid biosynthetic process and branched-chain amino acid catabolic process. Located in mitochondrial matrix. Human ortholog(s) of this gene implicated in hypervalinemia and hyperleucine-isoleucinemia. Orthologous to several human genes including BCAT2 (branched chain amino acid transaminase 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

BAT1 and BAT2 differential expression and subcellular relocalization has resulted in distribution of the biosynthetic and catabolic roles of ancestral BCAT in two isozymes improving BCAA metabolism and constituting an adaptation to facultative metabolism.
Title: Saccharomyces cerevisiae Bat1 and Bat2 aminotransferases have functionally diverged from the ancestral-like Kluyveromyces lactis orthologous enzyme.
adjustment of BAT gene expression could play an important role in assisting winemakers in their endeavour to produce wines with specific flavour profiles.
