TP53I3 (tumor protein p53 inducible protein 3)

Gene

• Entrez ID: 9540
• Gene name: Tumor protein p53 inducible protein 3
• Gene symbol: TP53I3
• Synonyms (NCBI Gene): PIG3
• Chromosome: 2
• Chromosome location: 2p23.3
• Summary: The protein encoded by this gene is similar to oxidoreductases, which are enzymes involved in cellular responses to oxidative stresses and irradiation. This gene is induced by the tumor suppressor p53 and is thought to be involved in p53-mediated cell dea
