ABSTRACT Previous studies defined pUL84 of human cytomegalovirus as an essential regulatory protein with nuclear localization that was proposed to act during initiation of viral-DNA synthesis. Recently, we demonstrated that a complex domain of 282 amino acids within pUL84 functions as a nonconventional nuclear localization signal. Sequence inspection of this domain revealed the presence of motifs with homology to leucine-rich nuclear export signals. Here, we report the identification of two functional, autonomous nuclear export signals and show that pUL84 acts as a CRM-1-dependent nucleocytoplasmic shuttling protein. This suggests an unexpected cytoplasmic role for this essential viral regulatory protein.

Nuclear localization signal sequence is required for VACM-1/CUL5-dependent regulation of cellular growth
