Also available are antibodies against a specific histone modification like H3 tri methyl K4.
and silencing is thought to involve a dynamic association of the HP1β chromodomain with the tri-methylated Histone H3 Me(3)K9H3.
It consists of two copies of each of the four core histone proteins (H2A, H2B, H3 and H4).
histone H3 | Histone H3 | Histone H2B | Histone H2A | Histone H4 | Histone deacetylase |
The cladogram was based on DNA sequences of both nuclear histone H3 and mitochondrial cytochrome-c oxidase I (COI) protein-coding gene regions.
