Background

  • Function

    Histone H2A.X is a 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

  • Subcellular Localization

    Nucleus; Chromosome

  • Subunit

    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 (Probable). Interacts with numerous proteins required for DNA damage signaling and repair when phosphorylated on Ser-140 (PubMed:12419185, PubMed:12607005, PubMed:15201865). These include MDC1, TP53BP1, BRCA1 and the MRN complex, composed of MRE11, RAD50, and NBN (PubMed:12419185, PubMed:12607005, PubMed:15201865). Interaction with the MRN complex is mediated at least in part by NBN (PubMed:12419185). Also interacts with DHX9/NDHII when phosphorylated on Ser-140 and MCPH1 when phosphorylated at Ser-140 or Tyr-143 (PubMed:15613478). Interacts with ARRB2; the interaction is detected in the nucleus upon OR1D2 stimulation (PubMed:16820410). Interacts with WRAP53/TCAB1 (PubMed:26734725, PubMed:27715493). Interacts with HDGFL2 (PubMed:26721387). Interacts with DNA damage up-regulated protein DDUP (PubMed:35849344). Forms a complex with DDUP and RAD18 following DDUP phosphorylation (PubMed:35849344)
