WebbAll histone core proteins can be ubiquitylated, but H2A and H2B are most commonly and are two of the most highly ubiquitylated proteins in the nucleus (Cao et al., 2012). Histone ubiquitylation plays a central role in the DNA damage response. Monoubiquitylation of histones H2A, H2B, and H2AX is found at sites of DNA double-strand breaks. Webb15 aug. 2024 · DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access the DNA as easily, so the gene is turned “off.” When histones are loosely packed, more DNA is exposed or not wrapped around a histone and can be accessed by proteins that ‘read’ the gene, so …
