Epstein-Barr Virus DNA Replication
Epstein-Barr virus (EBV) and its close relatives are the only known viruses that have two fully independent systems for replicating their genomes, one that supports virus production during active or "lytic" infection, and a second one that operates during latent stages of infection to allow the circular viral genomes to be duplicated during each cell division cycle. Although EBV's system of lyt...
متن کاملPlasticity of DNA Replication Initiation in Epstein-Barr Virus Episomes
In mammalian cells, the activity of the sites of initiation of DNA replication appears to be influenced epigenetically, but this regulation is not fully understood. Most studies of DNA replication have focused on the activity of individual initiation sites, making it difficult to evaluate the impact of changes in initiation activity on the replication of entire genomic loci. Here, we used singl...
متن کاملReplication of Epstein-Barr viral DNA.
Epstein-Barr virus (EBV) is a paradigm for human tumor viruses: it is the first virus recognized to cause cancer in people; it causes both lymphomas and carcinomas; yet these tumors arise infrequently given that most people in the world are infected with the virus. EBV is maintained extrachromosomally in infected normal and tumor cells. Eighty-four percent of these viral plasmids replicate each...
متن کاملU2 region of Epstein-Barr virus DNA may encode Epstein-Barr nuclear antigen 2.
Sequence analysis of the U2 regions of the B95-8 and AG876 Epstein-Barr virus (EBV) isolates reveals divergence within a long open reading frame previously identified as encoding 1.5 kilobases of the 3' end of a viral RNA expressed in latently infected, growth-transformed, B-lymphocyte cell lines. Differences among EBV isolates within the U2 open reading frame are shown to correlate with differ...
متن کاملComplex protein-DNA dynamics at the latent origin of DNA replication of Epstein-Barr virus.
The sequential binding of the origin recognition complex (ORC), Cdc6p and the minichromosome maintenance proteins (MCM2-7) mediates replication competence at eukaryotic origins of DNA replication. The latent origin of Epstein-Barr virus, oriP, is a viral origin known to recruit ORC. OriP also binds EBNA1, a virally encoded protein that lacks any activity predicted to be required for replication...
