Target

  • Function

    Variant histone H2A which replaces conventional H2A in a subset of nucleosomes where it represses transcription. 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. Involved in stable X chromosome inactivation. Inhibits the binding of transcription factors and interferes with the activity of remodeling SWI/SNF complexes. Inhibits histone acetylation by EP300 and recruits class I HDACs, which induces an hypoacetylated state of chromatin. In addition, isoform 1, but not isoform 2, binds ADP-ribose and O-acetyl-ADP-ribose, and may be involved in ADP-ribose-mediated chromatin modulation.
  • Tissue specificity

    Ubiquitous.
  • Sequence similarities

    Contains 1 histone H2A domain.
    Contains 1 Macro domain.
  • Post-translational
    modifications

    Monoubiquitinated at either Lys-116 or Lys-117. May also be polyubiquitinated. Ubiquitination is mediated by the CUL3/SPOP E3 complex and does not promote proteasomal degradation. Instead, it is required for enrichment in inactive X chromosome chromatin.
  • Cellular localization

    Nucleus. Chromosome. Enriched in inactive X chromosome chromatin and in senescence-associated heterochromatin.

    ab183041 was shown to specifically react with mH2A1 when mH2A1 knockout samples were used. Wild-type and mH2A1 knockout samples were subjected to SDS-PAGE. Ab183041 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 10000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab183041).

     

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of mouse liver from wild-type and mH2A1/2 knock out tissue sections labeling mH2A1 with ab183041 at 1/400 dilution. Sections were fixed in formaldehyde; heat mediated antigen retivial was performed using a citrate buffer pH 6. An undiluted polyclonal horse anti-rabbit IgG (HRP-conjugated) was used as the secondary antibody.
