New non-coding lytic transcripts derived from the Epstein Barr virus latency origin of replication oriP are hyper-edited, bind the paraspeckle protein, NONO/p54nrb, and support lytic viral transcription

ABSTRACT: We have previously shown that the Epstein-Barr virus (EBV) likely encodes hundreds of viral long non-coding RNAs (vlncRNAs) that are expressed during reactivation. Here we show that the EBV latency origin of replication (oriP) is transcribed bi-directionally during reactivation and that both leftward (oriPtLs) and rightward transcripts (oriPtRs) are largely localized in the nucleus. While the oriPtLs are most likely non-coding, at least some of the oriPtRs contain the BCRF1/vIL10 open reading frame. Nonetheless, oriPtR transcripts with long 5’UTRs may partially serve non-coding functions. Both oriPtL and oriPtR transcripts are expressed with late kinetics and their expression is inhibited by phosphonoacetic acid. RNA-seq analysis showed that oriPtLs and oriPtRs exhibited extensive “hyper-e
