The Epstein-Barr virus early protein EB2 (also called BMLF1, Mta, or SM), which allows the nuclear export of a subset of early and late viral mRNAs derived from intronless genes, is essential for the production of infectious virions. An important feature of mRNA export factors is their capacity to shuttle continuously between the nucleus and the cytoplasm. In a previous study, we identified a novel CRM1-independent transferable nuclear export signal (NES) at the N terminus of EB2, between amino acids 61 and 146. Here we show that this NES contains several small arginine-rich domains that cooperate to allow efficient interaction with TAP/NXF1. Recruitment of TAP/NXF1 correlates with this NES-mediated efficient nuclear export when it is fused to a heterologous protein. Moreover, the NES can export mRNAs bearing MS2 RNA-binding sites from the nucleus when tethered to the RNA via the MS2 phage coat protein RNA-binding domain.
