WRN RQC

Ken Kitano and colleagues have co-crystallised the RecQ C-terminal (RQC) domain of human WRN bound to a DNA duplex. In their recent Structure paper, they describe how the RQC domain interacts with a blunt end of the duplex and, surprisingly, … Continue reading

RecQ and recombination-based DNA repair

Dharmendra Kumar Singh and colleagues wrote an article in the Biogerontology journal presenting the various roles of human RecQ helicases in recombination-based DNA repair. The physiological consequences of RecQ defects in the development of cancer and premature aging were also … Continue reading

human exonuclease 1 and BLM helicase

In a recent paper by Amitabh Nimonkar and colleagues, it was established that human BLM helicase, a member of the RecQ family, stimulates human exonuclease 1 (hExo1), a 5′ – 3′ double-stranded DNA exonuclease … “Stimulation of DNA resection by … Continue reading

WRN mini-review

In a recent issue of DNA Repair [7 (2008) 1776–1786], Julia Sidorova reviews the role of WRN in preserving DNA integrity during replication and propose that WRN can function in coordinating replication fork progression with replication stress-induced fork remodeling. She … Continue reading
