Predicted to enable L-tyrosine-2-oxoglutarate transaminase activity. Predicted to be involved in L-phenylalanine catabolic process and tyrosine catabolic process. Predicted to act upstream of or within aromatic amino acid family catabolic process and biosynthetic process. Human ortholog(s) of this gene implicated in tyrosinemia and tyrosinemia type II. Orthologous to human TAT (tyrosine aminotransferase).
