title: Relative rates of RNA synthesis across the genome of Epstein-Barr virus are highest near oriP and oriLyt.
abstract: The rates of Epstein-Barr virus transcription were measured in isolated nuclei from marmoset and human lymphoblasts transformed in vitro. In B95-8, a marmoset B-lymphoid cell line, the most frequently transcribed viral genes are the EBERs (small nuclear RNAs) and BHLF-1 (encoding a lytic-phase gene product). The EBERs and BHLF-1 genes are separated by nearly 50 kilobase pairs on the Epstein-Barr virus genome and lie adjacent to (less than 300 base pairs from) oriP and oriLyt, respectively. oriP and oriLyt are putative origins of viral DNA replication, and each is associated with a transcriptional enhancer element. Among the human B-lymphoblastoid cell lines tested, only the transcription of EBERs predominates.
