DIO3 (iodothyronine deiodinase 3)

Gene

• Entrez ID: 1735
• Gene name: Iodothyronine deiodinase 3
• Gene symbol: DIO3
• Synonyms (NCBI Gene): 5DIII, D3, DIOIII, TXDI3
• Chromosome: 14
• Chromosome location: 14q32.31
• Summary: The protein encoded by this intronless gene belongs to the iodothyronine deiodinase family. It catalyzes the inactivation of thyroid hormone by inner ring deiodination of the prohormone thyroxine (T4) and the bioactive hormone 3,3`,5-triiodothyronine (T3)
