功能： 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, including NF-kappa-B, 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 . ; [Isoform 1]: Binds ADP-ribose and O-acetyl-ADP-ribose, and may be involved in ADP-ribose-mediated chromatin modulation . Increases the expression of genes involved in redox metabolism, including SOD3 . ; [Isoform 2]: Represses SOD3 gene expression.
