About BCAT1

Cytogenetic location: 12p12.1 Genomic coordinates (GRCh38): 12:24,810,024-24,949,101 (from NCBI)

This gene has 10 transcripts (splice variants), 205 orthologues and 1 paralogue. Broad expression in placenta (RPKM 7.3), pancreas (RPKM 6.7) and 22 other tissues.

Summary

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.
