      Alternate Names
      • H2A histone family, member Z
      • H2AZ histone
      Background InformationH2A.Z, also known as H2AFZ, is a variant of histone H2A variant that is highly conserved from yeast to humans. Like other histone variants, H2A.Z is encoded by a unique gene, resulting in a slightly divergent type of H2A with specialized functions. H2A.Z is involved in chromatin compaction by stabilizing the histone octamer within the nucleosome. It promotes gene expression through the creation of an open domain of chromatin that is more easily transcribed. H2A.Z is nonrandomly distributed throughout the genome, targeted primarily to pericentric heterochromatin, but excluded from the inactive X chromosome and the nucleolus. H2A.Z is associated with both euchromatin and facultative heterochromatin. DNA methylation can influence chromatin structure and effect gene silencing by excluding H2A.Z, and likewise, H2A.Z protects genes from DNA methylation. Thus, H2A.Z plays a role in regulating heterochromatin silencing and is involved in transcriptional control.

      Entrez Gene Number
      Entrez Gene SummaryHistones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene encodes a member of the histone H2A family. Several transcript variants encoding different isoforms, have been identified for this gene.

      UniProt Number
      UniProt SummaryFUNCTION: Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. 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 the formation of constitutive heterochromatin. May be required for chromosome segregation during cell division. Ref.7

      SUBUNIT STRUCTURE:The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA. H2A or its variant H2AFZ forms an heterodimer with H2B. H2AFZ interacts with INCENP By similarity.


      PTM: Monoubiquitination of Lys-122 gives a specific tag for epigenetic transcriptional repression.

      Acetylated on Lys-5, Lys-8 and Lys-12 during interphase. Acetylation disappears at mitosis By similarity.

      Not phosphorylated By similarity.

      SIMILARITY: Belongs to the histone H2A family.

      MOLECULAR WEIGHT: is 13413.4 Da from positions 2 - 128. Determined by ESI. Monoisotopic, not modified. Ref.8 Ref.10 Ref.11
