Phosphorylation of histone tails

WebCovalent modifications to histone tails, including methylation, acetylation, ubiquitination, sumoylation, citrullination, and phosphorylation, are well-correlated with chromatin structure (euchromatin versus heterochromatin) and accessibility, which in turn impacts transcriptional activation/silencing. For instance, histone acetylation (e.g ...
