Background: In vivo, histones are wrapped around by DNA in chromatin. Therefore, nucleosomes are more physiologically relevant substrates than histones and histone-derived peptides for in vitro studies. More importantly, some histone methyltransferases are signifcantly more active, as well as specifc, when using nucleosomal substrates in HMT assays, such as DOT1L and NSD family enzymes. Nucleosomes are also widely used in histone methyltransferase screening assays to identify small molecular inhibitors for drug discovery. Nuclear core histone H3 exist as several variants: H3.1, H3.2, H3.3, CENP-A and H3t. These variants have been suggested to have specific functions in the regulation of gene expression and genome stability. In mammals, histone H3 non-centromeric variants, H3.1, H3.2 and H3.3, differ in their chromatin deposition patterns and PTMs despite having a high degree of sequence similarity. H3.1 and H3.2, which are enriched in repressive chromatin marks, are predominantly expressed during S-Phase and deposited in DNA synthesis-coupled fashion during DNA replication and repair. In contrast, H3.3 is enriched in active chromatin marks and is expressed throughout the cell cycle. Canonical histone H3.2 is expressed during S phase and differs by only one amino acid residue from th variant histone H3.1, and four amino acid residues from histone H3.3. According to some researchers, H3.1 is preferentially acetylated and dimethylated on lysines 14 and 9, respectively, while H3.2 is preferentially subjected to trimethylation on lysine 27.
