DNA double-strand breaks are one of the most deleterious lesions for the cells, therefore understanding the macromolecular interactions of the DNA repair-related mechanisms is essential. DNA damage triggers transcription silencing at the damage site, leading to the removal of the elongating RNA polymerase II (S2P RNAPII) from this locus, which provides accessibility for the repair factors to the lesion. We previously demonstrated that following transcription block, p53 plays a pivotal role in transcription elongation by interacting with S2P RNAPII. In the current study, we reveal that p53 is involved in the fine-tune regulation of S2P RNAPII ubiquitylation. Furthermore, we emphasize the potential role of p53 in delaying the premature ubiquitylation and the subsequent chromatin removal of S2P RNAPII as a response to transcription block.
