Translesion Synthesis of the N2-2′-Deoxyguanosine Adduct of the Dietary Mutagen IQ in Human Cells: Error-Free Replication by DNA Polymerase κ and Mutagenic Bypass by DNA Polymerases η, ζ, and Rev1
Translesion synthesis (TLS) of the N(2)-2'-deoxyguanosine (dG-N(2)-IQ) adduct of the carcinogen 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) was investigated in human embryonic kidney 293T cells by replicating plasmid constructs in which the adduct was individually placed at each guanine (G1, G2, or G3) of the NarI sequence (5'-CG1G2CG3CC-3'). TLS efficiency was 38%, 29%, and 25% for the dG-N(2...
متن کاملDNA polymerases ζ and Rev1 mediate error-prone bypass of non-B DNA structures
DNA polymerase ζ (Pol ζ) and Rev1 are key players in translesion DNA synthesis. The error-prone Pol ζ can also participate in replication of undamaged DNA when the normal replisome is impaired. Here we define the nature of the replication disturbances that trigger the recruitment of error-prone polymerases in the absence of DNA damage and describe the specific roles of Rev1 and Pol ζ in handlin...

متن کاملTranslesion DNA Polymerases and Cancer
DNA repair has been regarded as an important barrier to carcinogenesis. The newly discovered field of translesion synthesis (TLS) has made it apparent that mammalian cells need distinct polymerases to efficiently and accurately bypass DNA lesions. Perturbation of TLS polymerase activity by mutation, loss of expression, etc. is expected to result in the accumulation of mutations in cells exposed...
متن کاملLow-fidelity DNA polymerases
Also known as.... Translesion synthesis polymerases. There are two of them in Escherichia coli, polymerases IV and V, and five in human cells, polymerases ζ, η, ι, κ and Rev1 (so a knowledge of the Greek alphabet is essential when discussing them). Except for polymerase ζ, they fall into a new DNA polymerase family, designated the Y-family. Depending on the lesion, polymerase and context, they ...
