Abstract

Background: ORC binds to replication origins, but human ORC does not exhibit apparent sequence-specificity. Results: G-quadruplex (G4)-preferable RNA or single-stranded DNA competes for DNA binding of ORC. Conclusion: HumanORCbinds preferentially toRNAand single-strandedDNAthat form G4, and the certain domain in ORC1 is involved in this binding. Significance: This ability may correlate with the G4-formable motif in human replication origins.
