POLI (DNA polymerase iota)

Gene

• Entrez ID: 11201
• Gene name: DNA polymerase iota
• Gene symbol: POLI
• Synonyms (NCBI Gene): RAD30B, RAD3OB, eta2
• Chromosome: 18
• Chromosome location: 18q21.2
• Summary: The protein encoded by this gene is an error-prone DNA polymerase involved in DNA repair. The encoded protein promotes DNA synthesis across lesions in the template DNA, which other polymerases cannot do. The encoded polymerase inserts deoxynucleotides acr
