Summaries for TAT Gene

Entrez Gene Summary for TAT Gene

  • This nuclear gene encodes a mitochondrial protein tyrosine aminotransferase which is present in the liver and catalyzes the conversion of L-tyrosine into p-hydroxyphenylpyruvate. Mutations in this gene cause tyrosinemia (type II, Richner-Hanhart syndrome), a disorder accompanied by major skin and corneal lesions, with possible mental retardation. A regulator gene for tyrosine aminotransferase is X-linked. [provided by RefSeq, Jul 2008]

GeneCards Summary for TAT Gene

TAT (Tyrosine Aminotransferase) is a Protein Coding gene. Diseases associated with TAT include Tyrosinemia, Type Ii and Hanhart Syndrome. Among its related pathways are Tyrosine metabolism and Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism. GO annotations related to this gene include pyridoxal phosphate binding and amino acid binding. An important paralog of this gene is KYAT3.

UniProtKB/Swiss-Prot for TAT Gene

  • Transaminase involved in tyrosine breakdown. Converts tyrosine to p-hydroxyphenylpyruvate. Can catalyze the reverse reaction, using glutamic acid, with 2-oxoglutarate as cosubstrate (in vitro). Has much lower affinity and transaminase activity towards phenylalanine.
