Background InformationHistone MacroH2A (mH2A), also known as H2AFY, is a vertebrate-specific histone variant associated with condensed, inactive heterochromatin. This histone variant consists of a histone H2A-like domain fused to a large non-histone region. mH2A has been shown to repress RNA polymerase II-driven transcription at the level of transcriptional initiation. The non-histone region of mH2A is directly involved in the repression of transcription, histone acetylation and blocking SWI/SNF and ACF nucleosome remodeling. This variant histone is enriched in chromatin of the female inactive X chromosome and in highly methylated CpG loci.

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. It replaces conventional H2A histones in a subset of nucleosomes where it represses transcription and participates in stable X chromosome inactivation. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq].

UniProt Number
UniProt SummaryFUNCTION: 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.

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. Interacts with SPOP. Part of a complex consisting of H2AFY, CUL3 and SPOP. Interacts with HDAC1 and HDAC2 (By similarity).

SUBCELLULAR LOCATION: Nucleus. Chromosome. Note: Enriched in inactive X chromosome chromatin and in senescence-associated heterochromatin. TISSUE SPECIFICTY: Ubiquitous.

PTM: 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.

MISCELLANEOUS: The number of individuals with antibodies against this antigen is 2-fold higher in pediatric patients with cancer compared to healthy controls.

SEQUENCE SIMILARITIES: Contains 1 histone H2A domain.

Contains 1 Macro domain.
