Replication origin-binding protein (IPR003450)

Short name: Replication_origin-bd

Overlapping homologous superfamilies


Domain relationships



This entry represents replication origin binding protein. It functions as a docking protein to recruit essential components of the viral replication machinery to viral DNA origins. In the presence of the major DNA-binding protein, it opens dsDNA which leads to a conformational change in the origin that facilitates DNA unwinding and subsequent replication [PMID: 7961904].
