Summary: Predicted to enable identical protein binding activity; ornithine aminotransferase activity; and pyridoxal phosphate binding activity. Predicted to be involved in arginine catabolic process to glutamate and arginine catabolic process to proline via ornithine. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; integumental system; respiratory system; and sensory organ. Used to study gyrate atrophy. Human ortholog(s) of this gene implicated in gyrate atrophy. Orthologous to human OAT (ornithine aminotransferase). [provided by Alliance of Genome Resources, Dec 2024]

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.
