The Epstein-Barr virus nuclear antigen 1 (EBNA1) protein binds to and activates DNA replication from oriP, the latent origin of DNA replication in Epstein-Barr virus. The crystal structure of the DNA-binding domain of EBNA1 bound to an 18 bp binding site was solved at 2.4 A resolution. EBNA1 comprises two domains, a flanking and a core domain. The flanking domain, which includes a helix that pr...

The association between Epstein-Barr virus subtype, human leukocyte antigen class I alleles, and the development of posttransplantation lymphoproliferative disorder was examined in a group of 25 bone marrow transplant recipients. A highly statistically significant correlation was observed between the human leukocyte antigen B51 allele and development of posttransplantation lymphoproliferative d...

A body cavity lymphoma-derived cell line (BC1), known to carry both Epstein-Barr virus (EBV) and human herpes virus type 8 (HHV-8; or Kaposi's sarcoma-associated herpesvirus, KSHV), was analysed for the expression of EBV-encoded, growth transformation-associated antigens and cellular phenotype by immunofluorescence staining, Western blotting, RT-PCR and flow cytometry. A similar phenotypic anal...
