The Amino Terminus of Epstein-Barr Virus (EBV) Nuclear Antigen 1 Contains AT Hooks That Facilitate the Replication and Partitioning of Latent EBV Genomes by Tethering Them to Cellular Chromosomes

Abstract excerpt

During latency, Epstein-Barr virus (EBV) is stably maintained as a circular plasmid that is replicated once per cell cycle and partitioned at mitosis. Both these processes require a single viral protein, EBV nuclear antigen 1 (EBNA1), which binds two clusters of cognate binding sites within the latent viral origin, oriP. EBNA1 is known to associate with cellular metaphase chromosomes through chromosome-binding...
