Objective The pre-mRNA of the Epstein–Barr virus LMP2 (latent membrane protein 2) has a region of unusual RNA structure that partially spans two consecutive exons and the entire intervening intron; suggesting RNA folding might affect splicing—particularly via interactions with human regulatory proteins. To better understand the roles of protein associations with this structured intronic region, we...
This review covers several computational methods for discovering structured non-coding RNAs in viruses and modeling their putative secondary structures. Here we will use examples from two target viruses to highlight these approaches: influenza A virus—a relatively small, segmented RNA virus; and Epstein–Barr virus—a relatively large DNA virus with a complex transcriptome. Each system has unique challenges...
EBER2 is an abundant nuclear noncoding RNA expressed by the Epstein-Barr virus (EBV). Probing its possible chromatin localization by CHART revealed EBER2’s presence at the terminal repeats (TRs) of the latent EBV genome, overlapping previously identified binding sites for the B cell transcription factor PAX5. EBER2 interacts with PAX5 and is required for the localization of PAX5 to the TRs. EBER2...
Sequences from the 5′ region of R2 retrotransposons of four species of silk moth are reported. In Bombyx mori, this region of the R2 messenger RNA contains a binding site for R2 protein and mediates interactions critical to R2 element insertion into the host genome. A model of secondary structure for a segment of this RNA is proposed on the basis of binding to oligonucleotide microarrays, chemical...
