General description

Monoclonal Anti-Acetyl-Histone H3 (Ac-Lys9) recognizes human histone H3 when acetylated on Lys9. Staining of the histone H3-Ac-Lys9 band in immunoblotting is specifically inhibited with the acetylated histone H3 immunizing peptide but not with the nonacetylated one.

Immunogen

synthetic, acetylated histone H3 peptide (amino acids 7-20, Ac-Lys9) corresponding to the N-terminus of human histone H3. The sequence is identical in many species including mouse, rat, bovine, chicken, frog, Drosophila, and C. elegans, and is highly conserved (single amino acid substitution) in Tetrahymena histone H3.

Application

Monoclonal Anti-acetyl-Histone H3 (Ac-Lys9) antibody may be used in various applications including ELISA, immunoblotting (approx. 17 kDa), and immunocytochemistry.

Biochem/physiol Actions

Acetyl-Histone H3 hav Acetylation of lysine residues within these N-terminal domains of histones by histone acetyl-transferase (HATs), including Gcn5p, PCAF, p300/CBP and TAFII250 is associated with transcriptional activation. This modification results in remodeling of the nucleosome structure into an open conformation more accessible to transcription complexes. Conversely, histone deacetylation by histone deacetylase (HDACs) is associated with transcription repression reversing the chromatin remodeling process. In most species, histone H3 is primarily acetylated at lysine 9, 14, 18, and 23. Acetylation at lysine 9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms. Acetylation of specific lysines in histone H3 is also associated with processes apart from transcription. During DNA replication, new histones are rapidly synthesized and assembled into replicated DNA. Histones H3 and H4 are brought to replicating chromatin in a pre-acetylated state that turns into a de-acetylated state after replication is completed and the newly assembled chromatin matures.

Chromatin structure plays a fundamental role in regulating processes that take place on the DNA, such as transcription, replication, and recombination, all of which occur on nucleosomal templates. Therefore, mapping the position of histones selectively modified and histone variants or non-histone components of chromatin in specific DNA sequences, can provide valuable insights into how these proteins (and their modifications) function in a chromatin context.
