HistoneH3 (23-34) is a peptide consisting of amino acid residues 23 to 34 of the histoneH3 protein. This peptide specifically includes lysine residues at positions 23 and 27, which can undergo methylation and acetylation modifications.
HistoneH3K27Me1 (23-34) is a peptide fragment of histoneH3 that corresponds to amino acid residues 24-35 of the human histoneH3.1 and H3.2 sequences. Monomethylation of histoneH3 at lysine 27 is associated with actively transcribed genes and positively correlates with H3K36 trimethylation. Levels of H3K27Me1 are increased in tumor tissue isolated from patients with metastatic hormone-na ve and castration-resistant prostate cancer. HistoneH3K27Me1 (23-34) has been used in epitope mapping of the lupus-derived monoclonal antibody BT164.
