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…

WebbHistones are the major protein component of chromatin and are subject to several different post-translational modifications, including methylation, acetylation, phosphorylation, ubiquitylation, and sumoylation.
