In vitro gap-directed translesion DNA synthesis of an abasic site involving human DNA polymerases epsilon, lambda, and beta
Original language description
DNA polymerase (pol) ? is thought to be the leading strand replicase in eukaryotes, whereas pols ? and ? are believed to be mainly involved in re-synthesis steps of DNA repair. DNA elongation by the human pol ? is halted by an abasic site (apurinic/apyrimidinic (AP) site). In this study, we present in vitro evidence that human pols ?, ?, and ? can perform translesion synthesis (TLS) of an AP site in the presence of pol ?, likely by initiating the 3OHs created at the lesion by the arrested pol ?. However, in the case of pols ? and ?, this TLS requires the presence of a DNA gap downstream from the product synthesized by the pol ?, and the optimal gap for efficient TLS is different for the two polymerases. Collectively, our in vitro results support the existence of a mechanism of gap-directed TLS at an AP site involving a switch between the replicative pol ? and the repair pols ? and ?.
