γH2AX does not, itself, cause chromatin decondensation, but within 30 seconds of ionizing radiation , RNF8 protein can be detected in association with γH2AX. [13] 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).

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). 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.

H2AX is a variant of histone H2A, one of the histone core molecules forming the nucleosome, and is a vital component in repairing DNA damage (1-4). Histone H2AX, Histone H2A.X, H2AX_HUMAN.

2010-02-04 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). 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. 2AX (H2AX) to γH2AX as part of the DNA repair process. In the procedure described, following immunostaining, automated fluorescent imaging and dual-mask spot (part number 8875S) was purchased from Cell Signaling Technology (Danvers, MA). Donkey anti-rabbit IgG secondary Wash sections in dH 2 O two times for 5 min each. Wash sections in wash buffer for 5 min. Block each section with 100–400 µl of preferred blocking solution for 1 hr at room temperature.

Phosphorylated on Ser-140 (to form gamma-H2AX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, and may also occur during meiotic recombination events and immunoglobulin class switching in lymphocytes. Gamma H2AX (gammaH2AX) is the phosphorylated version of histone H2AX and is a marker for double-stranded breaks (DSBs) caused by DNA damage (1-4).
