Alkaline proteins found in eukaryotic cell nuclei.
H1- 21.3kD H2a - 14.3kD H2b - 13.8kD H3 - 15.0kD H4 - 11.3kD
This eight unit protein wraps DNA into ever increasing coils of complexity and smallest size possible. Acetylated to give the protein winding and relaxing action.
histones act as spools araund which DNA winds, and play a role in gene regulations unlike nonhistone proteins that said your mon is ugly.... :)
