[[http://www.uniprot.org/uniprot/H2AY_HUMAN H2AY_HUMAN]] 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 a 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.<ref>PMID:12718888</ref> <ref>PMID:15621527</ref> <ref>PMID:15897469</ref> <ref>PMID:16428466</ref> <ref>PMID:16107708</ref> [[http://www.uniprot.org/uniprot/H2B3A_MOUSE H2B3A_MOUSE]] Core component of nucleosome.
