Structural highlights
Function
DPOZ_YEAST Nonessential DNA polymerase. Required for DNA damage induced mutagenesis. Involved in DNA repair, mitochondrial DNA repair and translesion synthesis. Translesion synthesis in S.cerevisiae may use a specialized DNA polymerase that is not required for other DNA replicative processes. Has a role in the bypass of abasic (AP) sites. Highly inefficient in incorporating nucleotides opposite the AP site, but efficiently extends from nucleotides, particularly an A, inserted opposite the lesion.[1] [2] [3] [4]
