Histone proteins are rich in Biology Questions

Histone variants are proteins that substitute for the core canonical histones (H3, H4, H2A, H2B) in nucleosomes in eukaryotes and often confer specific structural and functional features. The term might also include a set of linker histone (H1) variants, which lack a distinct canonical isoform. The differences between the core canonical histones and their variants can be summarized as follows: (1) canonical histones are replication-dependent and are expressed during the S-phase of cell c… WebbIn addition to the histones and non-histone proteins, some RNA is also found to be associated with the DNA in the chromosomes of eukaryotes.

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.
