PrimPol breaks replication barriers

Nat Struct Mol Biol. 2013 Dec;20(12):1348-50. doi: 10.1038/nsmb.2727.


Faithful bypass of replication forks encountering obstructive DNA lesions is essential to prevent fork collapse and cell death. PrimPol is a new human primase and translesion polymerase that is able to bypass fork-blocking UV-induced lesions and to restart replication by origin-independent repriming.
