FunctionREV1_HUMAN Deoxycytidyl transferase involved in DNA repair. Transfers a dCMP residue from dCTP to the 3'-end of a DNA primer in a template-dependent reaction. May assist in the first step in the bypass of abasic lesions by the insertion of a nucleotide opposite the lesion. Required for normal induction of mutations by physical and chemical agents.[1] [2] [3] [4] [5] Publication Abstract from PubMedREV1, REV3, and REV7 are pivotal proteins in translesion DNA synthesis, which allows DNA synthesis even in the presence of DNA damage. REV1 and REV3 are error-prone DNA polymerases and function as inserter and extender polymerases in this process, respectively. REV7 interacts with both REV1 and REV3, acting as an adaptor that functionally links the two, although the structural basis of this collaboration remains unclear. Here, we show the crystal structure of the ternary complex, composed of the C-terminal domain of human REV1, REV7, and a REV3 fragment. The REV1 C-terminal domain adopts a four-helix bundle that interacts with REV7. A linker region between helices 2 and 3, which is conserved among mammals, interacts with the beta-sheet of REV7. Remarkably, the REV7-binding interface is distinct from the binding site of DNA polymerase eta or kappa. Thus, the REV1 C-terminal domain might facilitate polymerase switching by providing a scaffold for both inserter and extender polymerases to bind. Our structure reveals the basis of DNA polymerase zeta (a complex of REV3 and REV7) recruitment to the stalled replication fork and provides insight into the mechanism of polymerase switching.
