The CysB motif of Rev3p involved in the formation of the four-subunit DNA polymerase ζ is required for defective-replisome-induced mutagenesis.

Abstract excerpt

Eukaryotic DNA replication is performed by high-fidelity multi-subunit replicative B-family DNA polymerases (Pols) α, δ and ɛ. Those complexes are composed of catalytic and accessory subunits and organized in multicomplex machinery: the replisome. The fourth B-family member, DNA polymerase zeta (Pol ζ), is responsible for a large portion of mutagenesis in eukaryotic cells. Two forms of Pol ζ have been identified,...
