A peptide fragment of histone H3
Histone H3 (1-20) is an N-terminal fragment of histone H3 that corresponds to amino acid residues 2-21 of the human histone H3 sequence. Histone H3 (1-20) contains lysine residues at positions 4 and 9 that are subject to methylation and acetylation and a serine residue at position 10 that is subject to phosphorylation, all of which have a role in the regulation of gene expression. Histone H3 (1-20) has been used as a control for modified histone H3 peptides to determine the effect of site-specific post-translational modifications during mitosis.
