Abstract

Genome integrity at replication forks Previous studies have indicated an undefined role in DNA replication for CENP-B, a DNA-binding protein associated with heterochromatin, centromeres and retrotransposon long terminal repeats (LTRs). Robert Martienssen and colleagues show that Sap1, which binds LTRs, promotes genomic instability when CENP-B activity is absent. CENP-B facilitates replication-fork progression through LTRs in a way that protects against rearrangements.
