Schematic illustration of the Epstein Barr virus (EBV) OriP and interacting viral and telomeric proteins. Organization of the OriP region where the family of repeats (F) and dyad symmetry (DS) regions are indicated. The enlarged region within the DS contains two EBV nuclear antigen (EBNA)1 binding sites (black box) adjacent to telomere-like sequences (red box) where EBNA1 and telomere-associated proteins bind and recruit proteins, such as Origin Recognition Complex (ORC) and MCM, that are involved in viral genome replication and maintenance. TRF1-interacting protein, TNKS, interacts with EBNA1 and regulates OriP replication.
