Deskripsi
The tumor suppressor BRCA2 protects stalled DNA replication forks from unrestrained degradation; however the mechanism whereby unprotected stalled forks are preserved and restarted has remained elusive. Here the authors show that the WRN helicase promotes stalled fork recovery and limits fork hyper-degradation in the absence of BRCA2 protection.
