Summaries for BCAT1 Gene

Entrez Gene Summary for BCAT1 Gene

  • This gene encodes the cytosolic form of the enzyme branched-chain amino acid transaminase. This enzyme catalyzes the reversible transamination of branched-chain alpha-keto acids to branched-chain L-amino acids essential for cell growth. Two different clinical disorders have been attributed to a defect of branched-chain amino acid transamination: hypervalinemia and hyperleucine-isoleucinemia. As there is also a gene encoding a mitochondrial form of this enzyme, mutations in either gene may contribute to these disorders. Alternatively spliced transcript variants have been described.

GeneCards Summary for BCAT1 Gene

BCAT1 (Branched Chain Amino Acid Transaminase 1) is a Protein Coding gene. Diseases associated with BCAT1 include Hyperleucine-Isoleucinemia and Pediatric Ependymoma. Among its related pathways are Pantothenate and CoA biosynthesis and Glucose / Energy Metabolism. GO annotations related to this gene include identical protein binding and L-leucine transaminase activity. An important paralog of this gene is BCAT2.
