A critical role of the 3' terminus of nascent DNA chains in recognition of stalled replication forks.


Arrest of replication forks by various internal and external threats evokes a myriad of cellular reactions, collectively known as DNA replication checkpoint responses. In bacteria, PriA is essential for restoration of stalled replication forks and recombinational repair of double-stranded DNA breaks and is a candidate sensor protein that may recognize… (More)
