WebJul 7, 2024 · Abstract. The ‘open’ and ‘compact’ regions of chromatin are considered to be regions of active and silent transcription, respectively. However, individual genes produce transcripts at different levels, suggesting that transcription output does not depend on the simple open-compact conversion of chromatin, but on structural variations in chromatin … WebKnockdown of Brd4 in human cells alleviates E2-mediated repression of HPV transcription. The E2-interacting domain at the extreme C terminus and the chromatin targeting activity of a bromodomain-containing region are both essential for the corepressor activity of Brd4.
