Histone H3K14Ac/H3K23Ac (1-24)-GGK-biotin is a peptide fragment of histone H3 that corresponds to amino acid residues 2-25 of the human histone H3 sequence. It is acetylated at lysine 14 and lysine 23 and biotinylated via a C-terminal GGK linker. Acetylation of H3K14 or H3K23 is associated with transcriptional activation and H3K14 acetylation is required for trimethylation of H3K4.1,2 H3K23 acetylation is decreased in wild-type but increased in uninephrectomized db/db mouse kidney.3
