RNA viruses exist as dynamic and diverse populations shaped by constant mutation and selection. Yet little is known about how the mutant spectrum contributes to virus evolvability and pathogenesis. Because several codon choices are available for a given amino acid, a central question concerns whether viral sequences have evolved to optimize not only the protein coding consensus, but also the DNA/RNA...
The human CCCTC-binding factor, CTCF, regulates transcription of the double-stranded DNA genomes of herpesviruses. The architectural complex cohesin and RNA Polymerase II also contribute to this organization. We profiled the occupancy of CTCF, cohesin, and RNA Polymerase II on the episomal genome of the Epstein–Barr virus in a cell culture model of latent infection. CTCF colocalizes with cohesin but...
