Replication stress induces specific enrichment of RECQ1 at common fragile sites FRA3B and FRA16D

Abstract excerpt

BACKGROUND: Stalled replication forks at common fragile sites are a major cause of genomic instability. RecQ helicases, a highly conserved family of DNA-unwinding enzymes, are believed to ease 'roadblocks' that pose challenge to replication fork progression. Among the five known RecQ homologs in humans, functions of RECQ1, the most abundant of all, are poorly understood. We previously determined that RECQ1...
