Differences in RNA polymerase II complexes and their interactions with surrounding chromatin on human and cytomegalovirus genomes
Abstract
Here the authors digested chromatin with DNA fragmentation factor (DFF) prior to chromatin immunoprecipitation (DFF-ChIP) to depict transcription complex interactions with neighboring nucleosomes in cells. Applying this method to human cytomegalovirus (HMCV)-infected cells, they find that the viral genome is underchromatinized, leading to fewer transcription complex interactions with nucleosomes.
