DNA Repair: DNA Polymerase ζ and Rev1 Break in
seen in this study for verbs, in the processing of time and temporal structure [10]. While Shapiro et al. [3] are admirably restrained in their interpretations, they outline how their results suggest there is some relationship between grammatical class and semantic representations. This is a far from trivial issue: from a classic psycho-linguistic perspective, semantic and syntactic representat...
متن کاملREV1 and polymerase ζ facilitate homologous recombination repair
REV1 and DNA Polymerase ζ (REV3 and REV7) play important roles in translesion DNA synthesis (TLS) in which DNA replication bypasses blocking lesions. REV1 and Polζ have also been implicated in promoting repair of DNA double-stranded breaks (DSBs). However, the mechanism by which these two TLS polymerases increase tolerance to DSBs is poorly understood. Here we demonstrate that full-length human...
متن کاملREV1 restrains DNA polymerase ζ to ensure frame fidelity during translesion synthesis of UV photoproducts in vivo
Exposure to ultraviolet light induces a number of forms of damage in DNA, of which (6-4) photoproducts present the most formidable challenge to DNA replication. No single DNA polymerase has been shown to bypass these lesions efficiently in vitro suggesting that the coordinate use of a number of different enzymes is required in vivo. To further understand the mechanisms and control of lesion byp...
متن کاملTranslesion synthesis of acetylaminofluorene-dG adducts by DNA polymerase zeta is stimulated by yeast Rev1 protein.
Translesion synthesis is an important mechanism in response to unrepaired DNA lesions during replication. The DNA polymerase zeta (Polzeta) mutagenesis pathway is a major error-prone translesion synthesis mechanism requiring Polzeta and Rev1. In addition to its dCMP transferase, a non-catalytic function of Rev1 is suspected in cellular response to certain types of DNA lesions. However, it is no...
متن کاملEukaryotic DNA polymerase ζ.
This review focuses on eukaryotic DNA polymerase ζ (Pol ζ), the enzyme responsible for the bulk of mutagenesis in eukaryotic cells in response to DNA damage. Pol ζ is also responsible for a large portion of mutagenesis during normal cell growth, in response to spontaneous damage or to certain DNA structures and other blocks that stall DNA replication forks. Novel insights in mutagenesis have be...
