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 DNA polymerase zeta in DNA interstrand crosslink repair.
DNA interstrand crosslinks (ICLs) are covalent linkages between two strands of DNA, and their presence interferes with essential metabolic processes such as transcription and replication. These lesions are extremely toxic, and their repair is essential for genome stability and cell survival. In this review, we will discuss how the removal of ICLs requires interplay between multiple genome maint...
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 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...
متن کاملATR Homolog Mec1 Controls Association of DNA Polymerase ζ-Rev1 Complex with Regions near a Double-Strand Break
DNA polymerase zeta (Polzeta) and Rev1 contribute to the bypassing of DNA lesions, termed translesion DNA synthesis (TLS). Polzeta consists of two subunits, one encoded by REV3 (the catalytic subunit) and the other encoded by REV7. Rev1 acts as a deoxycytidyl transferase, inserting dCMP opposite lesions. Polzeta and Rev1 have been shown to operate in the same TLS pathway in the budding yeast Sa...
