Figure 1.
Effect of MAGE-A4 on responses to DNA damage and replication stress. In cancer cells MAGE-A4-RAD18 promotes TLS thereby averting replication fork collapse and conferring DNA damage tolerance while increasing the risk of mutagenesis. The black and red arrows (and) indicate leading strand 5′–3′ DNA synthesis and the red “explosion” indicates a fork-stalling DNA lesion.
