Previously, we identified Syncytin1 to be expressed in human B cells and enhance EBV ability to undergo lytic replication. To gain mechanistic insight, we performed liquid chromatography tandem mass spectrometry (LC-MS/MS) on tryptic peptides from immunoprecipitated FLAG-tagged Syncytin-1 in latently infected EBV+ Burkitt lymphoma cells. This revealed a number of cellular proteins as potential Syncytin-1 interacting partners during latency and/or during the lytic phase as well as two EBV lytic phase proteins, the viral protein kinase and LF2, a negative regulator of EBV lytic gene transcription. We now find that Syncytin1 reduces the association between LF2 and the EBV replication and transcription activator to promote EBV lytic gene expression.
