Application: Histone H3 (5–23) is a synthetic peptide corresponding to amino acid residues 5–23 of the histone H3 N-terminal tail, a key regulatory region involved in chromatin structure and transcriptional control. This sequence contains multiple lysine residues that can undergo acetylation, methylation, and other post-translational modifications. Histone H3 (5–23) serves as a substrate for histone acetyltransferase enzymes and is commonly used in enzymatic activity assays. It is widely applied in epigenetics research to study histone modification dynamics, HAT activity, enzyme specificity, chromatin regulation, and modification-dependent gene expression mechanisms.
