H2A.X is phosphorylated at Ser139 by DNA-PK in response to cell death receptor activation, c-Jun N-terminal Kinase (JNK1) in response to UV-A irradiation, and p38 MAPK in response to serum starvation (5-8). H2A.X is constitutively phosphorylated on Tyr142 in undamaged cells by WSTF (Williams-Beuren syndrome transcription factor) (9,10).

At these sites of DNA damage, γ-H2AX appears to have a critical function in the recruitment of DNA repair factors and DNA damage-signaling proteins [ 12, 13 ]. Gamma-H2AX counts averaged over the 1500–3000 µm interval were significantly different from each other. i Time dependence of γ-H2AX signal appearance in the irradiated and bystander areas (γ-H2AX counts relative to the number of nuclei and corrected for background in non-irradiated paired cell dishes) for 1 and 20 Gy irradiation. This colocalization was taken to indicate that γH2AX has a pleiotropic function, which ranges from recruitment signaling, fixation of broken ends and facilitation of DSB repair (Fernandez-Capetillo et al., 2004). Phosphorylated H2AX is considered to be a biomarker for DNA double-strand breaks (DSB), but recent evidence suggests that γH2AX does not always indicate the presence of DSB. Here we demonstrate the bimodal dynamic of H2AX phosphorylation induced by ionizing radiation, with the second peak appearing when G2/M arrest is induced.

Predicted band size: 15 kDa. 15% This modification, called gamma-H2AX (phospho-Ser139), triggers cell cycle arrest and DNA damage response repair, which makes this assay particularly appropriate for studying genome stability, cell cycle, DNA repair, and more broadly as a biomarker for cancer and for aging process investigations.

H2A.X is required for checkpoint-mediated cell cycle arrest and DNA repair following double-stranded DNA breaks (1). DNA damage, caused by ionizing radiation, UV-light, or radiomimetic agents, results in rapid phosphorylation of H2A.X at Ser139 by PI3K-like kinases, including ATM, ATR, and DNA-PK (2,3).

DNA damage, caused by ionizing radiation, UV-light, or radiomimetic agents, results in rapid phosphorylation of H2A.X at Ser139 by PI3K-like kinases, including ATM, ATR, and DNA-PK (2,3). Phosphorylated H2AX (gamma-H2AX) is essential to the efficient recognition and (or) repair of DNA double strand breaks (DSBs), and many molecules, often thousands, of H2AX become rapidly phosphorylated at the site of each nascent DSB. An antibody to gamma-H2AX reveals that this highly amplified process generates nuclear foci. The gamma-H2AX assay was capable of detecting DNA damage at levels 100-fold below the detection limit of the alkaline comet assay. The gamma-H2AX signal was quantitative with a linear increase of the gamma-H2AX signal over two orders of magnitude. Phosphorylation of the Ser-139 residue of the histone variant H2AX, forming γH2AX, is an early cellular response to the induction of DNA double-strand breaks. Detection of this phosphorylation In basal conditions, though, you may expect vary faint gamma-H2AX band and a strong H2AX one.
