Histone H4 is one of the four proteins that are present in the nucleosome, the basic repeating unit subunit of chromatin, consisting of 147 base pairs of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3 and H4). Acetylation of H4 lysine 8 (by CBP adn p300 in mammals) is associated with transcriptional activation.
Histone H4 K8Ac Antibody Immunogen:
Synthetic peptide corresponding to the amino terminus of human histone H4 acetylated at lysine 8.
