Histone H3, also known as Histone H3.1t (H3/t), H3t, H3/g, and encoded by the gene name HIST3H3/ H3FT, is a core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Therefore, histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the ′beads on a string′ structure. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine. High levels of phosphorylation of Histone H3 are associated with mitosis.

Lysine residues in histones and other proteins can be modified by post-translational modifications that encode regulatory information1. Lysine acetylation and methylation are especially important for regulating chromatin and gene expression2-4. Pathways involving these post-translational modifications are targets for clinically approved
