Single-molecule imaging reveals multiple pathways for the recruitment of translesion polymerases after DNA damage.

Abstract excerpt

Unrepaired DNA lesions are a potent block to replication, leading to replication fork collapse, double-strand DNA breaks, and cell death. Error-prone polymerases overcome this blockade by synthesizing past DNA lesions in a process called translesion synthesis (TLS), but how TLS polymerases gain access to the DNA template remains poorly understood. In this study, we use particle-tracking PALM to image live...
