Summary: Enables branched-chain-amino-acid transaminase activity. Acts upstream of or within branched-chain amino acid metabolic process; cellular response to leukemia inhibitory factor; and regulation of hormone levels. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study maple syrup urine disease. Human ortholog(s) of this gene implicated in hypervalinemia and hyperleucine-isoleucinemia. Orthologous to human BCAT2 (branched chain amino acid transaminase 2).

leucine supplementation increased the expression of enzymes (BCAT1, BCAT2 and BCKDK) that metabolize branched-chain amino acids.
Title: Oral leucine supplementation is sensed by the brain but neither reduces food intake nor induces an anorectic pattern of gene expression in the hypothalamus.
knockout caused increased expression of orexigenic neuropeptides and an avoidance of branched chain amino acid but not high-protein diets

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.

See identical proteins and their annotated locations for NP_001229981.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at a downstream start codon, compared to variant 1. The encoded isoform (2) has a shorter N-terminus than isoform 1. Variants 2 and 3 both encode the same isoform (2).
