Summaries for BCAT2 Gene

Entrez Gene Summary for BCAT2 Gene

  • This gene encodes a branched chain aminotransferase found in mitochondria. The encoded protein forms a dimer that catalyzes the first step in the production of the branched chain amino acids leucine, isoleucine, and valine. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

GeneCards Summary for BCAT2 Gene
