Webb14 apr. 2024 · Additionally, the cis-regulatory landscape of cancer includes aberrant super-enhancers that are not present in normal cells. The landscape of super-enhancers in cancer is characterized by high levels of histone H3K27 acetylation and bromodomain-containing protein 4 (BRD4), and Mediator complex. Webb27 nov. 2014 · One of the multiple regulatory mechanisms of p53 is its homo-tetramerization that masks one of its NES sequences. Dissociation of this tetramer is required for its nuclear export . Binding of proteins to RNA and DNA can also modulate the intermolecular masking of localization signal.
