The Epstein-Barr virus (EBV) nuclear antigen 2 (EBNA2) gene product is the key regulator of the latent genes of EBV and essential for EBV-mediated transformation of human primary B cells. Viral mutants were constructed carrying a deletion of the EBNA2 conserved region 4 (CR4). Primary resting B cells infected with the DeltaCR4-EBNA2 mutant virus were dramatically impaired for B cell transformation. Lymphoblastoid cell lines (LCLs) established with this mutant EBV revealed a prolonged population doubling time when cells were cultivated at low cell densities, which are not critical for wild-type-infected cells. Low-level spontaneous cell death occurred when the cells were cultivated at suboptimal cell densities. The phenotype of B cells and LCLs infected with the DeltaCR4-EBNA2 mutant virus indicated that the CR4 region of EBNA2 specifically contributes to the viability of the cells rather than affecting cell division rates.
