Acetylated histone peptide

Acetylated histone peptides are synthetic or cell-derived fragments of histone proteins that contain one or more lysine residues modified by acetylation, a key post-translational modification in chromatin biology. These peptides serve as molecular tools for studying the molecular recognition of acetyl-lysine by reader domains such as bromodomains and for dissecting the role of histone acetylation in the regulation of transcription, DNA repair, and cell cycle progression[1][3][4][5]. Acetylated histone peptides are not therapeutic targets themselves but represent a class of biochemical substrates used for structural, biochemical, or cellular assays investigating chromatin function. Mistaking them for a target (such as an enzyme, receptor, or transporter) is incorrect; in biological and therapeutic contexts, the true targets are typically the enzymes (histone acetyltransferases, deacetylases) or reader proteins (e.g., bromodomain-containing proteins) that interact with these acetylated motifs[1][2][3]. In summary, "acetylated histone peptide" is not a canonical drug target and is a nonspecific term describing a modified peptide tool used in epigenetics research. If a specific histone, modification site, or reader/protein is of interest, providing its precise name would enable a structured and accurate record.
