Mutations in the ubiquitin binding UBZ motif of DNA polymerase eta do not impair its function in translesion synthesis during replication.

Abstract excerpt

Treatment of Saccharomyces cerevisiae cells with DNA-damaging agents elicits lysine 164-linked PCNA monoubiquitination by Rad6-Rad18. Recently, a number of ubiquitin (Ub) binding domains (UBDs) have been identified in translesion synthesis (TLS) DNA polymerases and it has been proposed that the UBD in a TLS polymerase affects its binding to Ub on PCNA and that this binding mode is indispensable for a TLS...
