Histone H3K9Me3 (3-17) is an N-terminal peptide fragment of histone H3 that corresponds to amino acid residues 4-18 of the human histone H3 sequence. Trimethylation of histone H3 at lysine 9 is associated with gene repression, prevents transcription factor binding, and is a target of the heterochromatin protein 1 (HP1) family proteins CBX1, CBX3, and CBX5.1,2 It is recognized by the plant homeodomain fingers of chromodomain helicase DNA binding protein 4 (CHD4), a member of the NuRD deacetylase complex that is upregulated in a variety of cancers and implicated in the DNA damage response.3
