H2A is considered a core histone, along with H2B, H3 and H4. Core formation first occurs through the interaction of two H2A molecules. [3] Then, H2A forms a dimer with H2B; the core molecule is complete when H3-H4 also attaches to form a tetramer. Sequence variants [ edit] Histone H2A is composed of … See more Histone H2A is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. The other histone proteins are: H1, H2B, H3 and H4. See more Histones are proteins that package DNA into nucleosomes. Histones are responsible for maintaining the shape and structure of a … See more H2A consists of a main globular domain, an N-terminal tail and a C-terminal tail. Both tails are the location of post-translational modification. Thus far, researchers have not identified any secondary structures that arise in the tails.
