  • 功能：
    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. Required for checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for efficient repair of DNA double strand breaks (DSBs) specifically when modified by C-terminal phosphorylation.
  • 基因功能参考文献：
    1. H2AX has a physiologic function in mediating influences of oxidative stress on NRF2-transcriptional targets and behavior PMID: 29670103
    2. 14days of variable stress, but not a single stress exposure, was associated with increased bed nucleus of the stria terminalis levels of gammaH2AX 24h after termination of the stress paradigm. Phosphorylation levels of a pair of kinases associated with the DNA damage response, glycogen synthase kinase 3 beta (GSK3beta) and p38 mitogen-activated protein kinase (MAPK) were also elevated following variable stress. PMID: 29352998
    3. The expansion of all three waves of H2AX phosphorylation from the leptotene to pachytene stages is regulated by MOF in meiosis. PMID: 29795555
    4. The results propose a model in which Aurora B-mediated H2AX-phosphorylated serine 121 probably provide a platform for Aurora B autoactivation circuitry at centromeres and thus play a pivotal role in proper chromosome segregation. PMID: 27389782
    5. TSSK6 is required for gammaH2AX formation during spermiogenesis, and also link gammaH2AX to the histone-to-protamine transition and male fertility. PMID: 28389581
    6. Our data show that gammaH2AFX enrichment extends as far as 9-15 Mb of the annotated genomic sequence of the q-arms of the translocated chromosomal trivalents and that both gammaH2AFX and H3.3 levels are reduced over the X chromosome. Our data are also suggestive of an asymmetry in gammaH2AFX and H3.3 enrichment with a bias toward the non-translocated homolog. PMID: 27090237
    7. Results suggest activation of H2AX via promoter demethylation in specific populations of basal mammary cells that is induced by a signal from neighboring luminal cells with hyper STAT5 activity. PMID: 27260000

    10. The s observe that persistent accumulation of reactive oxygen species, due to a deficient JunD-/Nrf2-antioxidant response, reduces H2AX protein levels. This effect is mediated by an enhanced interaction of H2AX with the E3 ubiquitin ligase RNF168, which is associated with H2AX poly-ubiquitination and promotes its degradation by the proteasome. PMID: 27006338
    11. The findings highlight specific non-overlapping functions of PARP1 and PARP2 at H2AX-deficient chromatin during replicative phases of the cell cycle and uncover a unique requirement for PARP1 in nonhomologous end-joining-deficient cells. PMID: 27373144
    12. Unlike directly induced DSBs, secondary DSBs were not efficiently repaired, although Rad51 and 53BP1 were recruited to these sites. H2AX was dramatically stabilized in response to DSBs directly caused by gamma-rays, enabling gammaH2AX foci formation and DSB repair, whereas H2AX was barely stabilized in response to secondary DSBs, in which gammaH2AX foci were small and DSBs were not efficiently repaired PMID: 27251002

    34. monoubiquitination of H2AX is an important step for DNA damage response PMID: 21690091
    35. These data suggest that, at long times after irradiation, mechanisms additional to impairment of DNA break repair may account for the long persistence of gamma-H2AX foci in male germ cells. PMID: 21498842
