Abstract

To investigate the importance of the Epstein-Barr virus (EBV) glycoprotein 110 (gp110) tail domain in the intracellular localization of gpl10 and virus lyric replication, three carboxy-terminal truncation mutants of gp110 wore constructed. Deletion of 16 amino acids from the carboxyl- terminal tail resulted in gp110 intracellular localization which was indistinguishable from that of wild-type gp110, whereas deletion of either 41 or 56 amino acids from the carboxyl-terminal tall of gp110 resulted in loss of retention of gp110 in the endoplasmic reticulum and nuclear membrane. None of the gp110 truncation mutants was able to complement EBV(gp110-)+ lymphoblastoid cell lines in transformation assays, indicating the importance of the gp110 tail domain in virus lyric replication. In electron microscopy analysis, no nucleocapsids or enveloped viruses were detected in EBV(gp110- )+ lymphoblastoid cell lines induced for lytic replication.
