The aim is to understand RNA polymerase II dynamics and the role of TAF1 in promoter-proximal pause release.
Utilized single-molecule imaging to observe RNA polymerase II interactions in live human cells.
Conducted single-cell analysis to measure heterogeneity in RNA polymerase II elongation.
Analyzed the effects of TAF1 degradation on RNA polymerase II clustering and pausing behavior.
Approximately 94% of chromatin-associated RNA polymerase II events dissociate within tens of seconds.
Acute degradation of TAF1 reduced RNA polymerase II clustering, indicating its role in promoting pause release.
Higher global pausing index observed with TAF1 depletion suggests altered transcriptional dynamics.
