Target Information
Histone H2A.X (H2AX) is a member of the histone H2A family, one of the four core histones forming the nucleosome core particle. In eukaryotes, DNA double-strand breaks (DSBs) trigger phosphorylation of serine 139 at the C-terminus of histone H2AX, resulting in γ-H2AX formation. This phosphorylation can be detected by Western blotting or immunofluorescence to assess DSB frequency.
Phosphorylation of H2AX is mediated by phosphatidylinositol 3-kinases, including ATM, DNA-PK, and ATR. H2A.X contains 143 amino acids and is synthesized both in G1 and S-phase. Two forms of its mRNA exist: a short replication-type (575 bases, lacking polyA) and a longer basal-type (1600 bases, containing polyA). The gene maps to human chromosome 11q23.2–q23.3. H2A.X plays a crucial role in chromatin structure and DNA repair signaling via MDC1 recruitment to DNA damage sites.
