RelevanceCore component of nucleosome which plays a central role in DNA double strand break (DSB) repair. 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. Post-translational modification for Saccharomyces cerevisiae: Phosphorylated to form H2AS128ph (gamma-H2A) in response to DNA double-strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks. Phosphorylation is dependent on the DNA damage checkpoint kinases MEC1/ATR and TEL1/ATM, spreads on either side of a detected DSB site and may mark the surrounding chromatin for recruitment of proteins required for DNA damage signaling and repair. Gamma-H2A interacts with ARP4, a shared component of the NuA4 histone acetyltransferase complex and the INO80 and SWR1 chromatin remodeling complexes, and serves to recruit first NuA4, mediating histone H4 acetylation, and subsequently the INO80/SWR1 complexes, facilitating DNA resection, to DSB sites. Gamma-H2A is required for sequestering cohesin around the break site, which is important for efficient post-replicative double-strand break repair by homologous recombination, holding the damaged chromatid close to its undamaged sister template. Gamma-H2A is removed from the DNA prior to the strand invasion-primer extension step of the repair process and subsequently dephosphorylated by PPH3, a component of the histone H2A phosphatase complex (HTP-C). Dephosphorylation is necessary for efficient recovery from the DNA damage checkpoint. N-acetylated by NAT4. Acetylated by ESA1, a component of the NuA4 histone acetyltransferase (HAT) complex, to form H2AK4ac and H2AK7ac. Glutamine methylation at Gln-106 (H2AQ105me) by NOP1 is specifically dedicated to polymerase I. It is present at 35S ribosomal DNA locus and impairs binding of the FACT complex. Sumoylated to from H2AK126su. May lead to transcriptional repression. Post-translational modification for Schizosaccharomyces pombe: Phosphorylated to form H2AS128ph (gamma-H2A) in response to DNA double-strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks. Phosphorylation is dependent on the DNA damage checkpoint kinases rad3/ATR and tel1/ATM, spreads on either side of a detected DSB site and may mark the surrounding chromatin for recruitment of proteins required for DNA damage signaling and repair. Gamma-H2A is required for recruiting crb2, a modulator of DNA damage checkpoint signaling, to DSB sites. Gamma-H2A is removed from the DNA prior to the strand invasion-primer extension step of the repair process and subsequently dephosphorylated. Dephosphorylation is necessary for efficient recovery from the DNA damage checkpoint. Acetylated by esa1 to form H2AK4ac and H2AK7ac.

Serially diluted ab181447 was bound to immobilised phospho (ab19828) - or control (ab19751) peptides (1 microgram x mL-1). The antibody was detected by HRP-labelled goat anti-rabbit IgG (ab97080; diluted 50000 times) and signal was developed with TMB substrate.This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab181447).
Dot blot analysis of Histone H2A (phospho S129) peptide (Lane 1), and non-phospho peptide (Lane 2), labeled using ab181447 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated secondary antibody at 1/1000 dilution.
Blocking/Dilution buffer: 5% NFDM/TBST.
Exposure time : 3 minutesThis data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab181447).
ab181447 was tested in Peptide Array against 501 different modified and unmodified histone peptides; each peptide is printed on the array at six concentrations (each in triplicate).This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab181447).
Circle area represents affinity between the antibody and a peptide: all antigen-containing peptides are displayed as red circles, all other peptides as blue circles. The affinity is calculated as area under curve when antibody binding values are plotted against the corresponding peptide concentration. Each circle area is normalized to the peptide with the strongest affinity.
The complete dataset, including full list of all peptides and information on the position of each peptide in the diagram, can be downloaded here.
Chromatin was prepared from Saccharomyces cerevisiae cells according to the Abcam X-ChIP protocol. Saccharomyces cerevisiae cells were treated with MMS at 2mg/ml for 1 h. Treated and non-treated Saccharomyces cerevisiae cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 2µg of ab181447 (blue), and 20µl of Anti rabbit IgG sepharose beads. 2μg of rabbit normal IgG was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab181447).
