Catalyzes the first reaction in the catabolism of the essential branched chain amino acids leucine, isoleucine, and valine. May also function as a transporter of branched chain alpha-keto acids. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family. Homodimer. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
