Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Acetylation is generally linked to gene activation. Acetylation on Lys-10 (H3K9ac) impairs methylation at Arg-9 (H3R8me2s). Acetylation on Lys-19 (H3K18ac) and Lys-24 (H3K24ac) favors methylation at Arg-18 (H3R17me).
Synonyms: H3Ac, Histone H3 acetyl, Histone H3Ac
Application: Western Blot Analysis:Acid-extracted proteins from HeLa cells treated with 5 mM sodium butyrate for 24 hours (Lane 2) and untreated HeLa cells (Lane 1) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-acetyl-Histone H3 (0.01 mug/mL).Proteins were visualized using a goat-rabbit secondary antibody conjugated to HRP and a chemilumnescence detection system (Please see figures).
