Function

[REV1_YEAST] Deoxycytidyl transferase involved in DNA repair. Transfers a dCMP residue from dCTP to the 3'-end of a DNA primer in a template-dependent reaction. May assist in the first step in the bypass of abasic lesions by the insertion of a nucleotide opposite the lesion. Required for normal induction of mutations by physical and chemical agents. Involved in mitochondrial DNA mutagenesis.^[1] ^[2] ^[3]

Publication Abstract from PubMed

Acrolein is generated as the end product of lipid peroxidation and is also a ubiquitous environmental pollutant. Its reaction with the N2 of guanine leads to a cyclic gamma-HOPdG adduct that presents a block to normal replication. We show here that yeast Rev1 incorporates the correct nucleotide C opposite a permanently ring-closed form of gamma-HOPdG (PdG) with nearly the same efficiency as opposite an undamaged G. The structural basis of this action lies in the eviction of the PdG adduct from the Rev1 active site, and the pairing of incoming dCTP with a "surrogate" arginine residue. We also show that yeast Polzeta can carry out the subsequent extension reaction. Together, our studies reveal how the exocyclic PdG adduct is accommodated in a DNA polymerase active site, and they show that the combined action of Rev1 and Polzeta provides for accurate and efficient synthesis through this potentially carcinogenic DNA lesion.
