Error-Prone DNA Polymerases: When Making a Mistake is the Only Way to Get Ahead. Annual Review of Genetics. Vol. ... Alison J. Rattray and Jeffrey N. Strathern ... Abstract Cells have high-fidelity polymerases whose task is to accurately replicate the genome, and low-fidelity polymerases with specialized functions.

By using fractionated cell extracts and purified recombinant proteins, we show that polη extends DNA synthesis from D loop recombination intermediates in which an invading strand serves as the primer. Our results indicate a dual function for polη at stalled replication forks: the promotion of translesion synthesis and the reinitiation of DNA synthesis by homologous recombination repair. The D loop extension activity of polη is unusual, as this reaction cannot be promoted by the replicative DNA polymerase δ or by other TLS polymerases such as polι.
