  • Function
    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.
  • Sequence similarities
    Belongs to the histone H2A family.
  • Post-translational
    The chromatin-associated form is phosphorylated on Thr-121 during mitosis.
    Deiminated on Arg-4 in granulocytes upon calcium entry.
    Monoubiquitination of Lys-120 by RING1 and RNF2/RING2 complex gives a specific tag for epigenetic transcriptional repression and participates in X chromosome inactivation of female mammals. It is involved in the initiation of both imprinted and random X inactivation. Ubiquitinated H2A is enriched in inactive X chromosome chromatin. Ubiquitination of H2A functions downstream of methylation of 'Lys-27' of histone H3. Monoubiquitination of Lys-120 by RNF2/RING2 can also be induced by ultraviolet and may be involved in DNA repair. Following DNA double-strand breaks (DSBs), it is ubiquitinated through 'Lys-63' linkage of ubiquitin moieties by the E2 ligase UBE2N and the E3 ligases RNF8 and RNF168, leading to the recruitment of repair proteins to sites of DNA damage. Monoubiquitination and ionizing radiation-induced 'Lys-63'-linked ubiquitination are distinct events.
    Phosphorylation on Ser-2 is enhanced during mitosis. Phosphorylation on Ser-2 by RPS6KA5/MSK1 directly represses transcription. Acetylation of H3 inhibits Ser-2 phosphorylation by RPS6KA5/MSK1.
    Symmetric dimethylation on Arg-4 by the PRDM1/PRMT5 complex may play a crucial role in the germ-cell lineage.

      Predicted band size: 14 kDa

      The blots were produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membranes were then blocked for an hour. 1 microgram per mL of control- (ab19751, lane 1 and 2) or phospho-peptides (ab19828, lane 3 and 4) were added to the primary antibody ab15083 (rabbit anti-Histone H2A (phospho S129) antibody; diluted 1:500) and loading control ab125247 (mouse anti-GAPDH antibody; diluted 1:20000) and the membranes were incubated with peptide/antibody mixture for 24 hours at 4°C. Antibody binding was detected using infrared (IR)-labelled goat anti-rabbit (green) and  IR-labelled goat anti-mouse (red; insert below) antibodies, diluted 1:20,000, for 1 hour at room temperature before imaging.

    • Serially diluted ab15083 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.

    • All batches of ab15083 are tested in Peptide Array against peptides to different Histone H2A modifications. Six dilutions of each peptide are printed on to the Peptide Array in triplicate and results are averaged before being plotted on to a graph. Results show strong binding to Histone H2A - phospho S129 (ab19828), indicating that this antibody specifically recognises the Histone H2A - phospho S129 modification.
