  • FunctionVariant 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. May be involved in stable X chromosome inactivation.
  • Sequence similaritiesContains 1 histone H2A domain.
    Contains 1 Macro domain.
  • Cellular localizationNucleus. Chromosome. Enriched in inactive X chromosome chromatin and in senescence-associated heterochromatin.
