These cells express a gene that causes a DNA damage response, leading to H2AX phosphorylation. 2013-11-01 · The phosphorylation of H2AX at Ser139 is a critical event in the series of early responses to IR-induced DNA double-strand breaks . Because of its early appearance and essential role in the DSB response, γH2AX is considered to be a sensitive biomarker for DSBs. Phosphorylated H2AX (designated as γH2AX) is rapidly accumulated over megabase domains at the sites of DSB (Shrivastav et al., 2008) and, therefore, can be microscopically visualized as discrete intranuclear “foci.” In higher eukaryotic cells, DSBs in chromatin promptly initiate the phosphorylation of the histone H2A variant, H2AX, at Serine 139 to generate γ-H2AX. 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). 2019-09-25 · Histone H2AX undergoes phosphorylation as an answer to DNA double-strand breaks, which in turn are part of the oncogenic procedure.

The phosphorylation of histone H2AX in Serine 139 (gamma‐H2AX) marks regions of DNA double strand breaks and contributes to the recruitment of DNA repair factors to the site of DNA damage. Gamma‐H2AX is used widely as DNA damage marker in vitro , but its use for genotoxicity assessment in vivo has not been extensively investigated. Histone H2A.X (H2AX) is a member of the histone H2A family which is one of the four core histones making up the nucleosome core particle. In eukaryotes, DNA double strand breaks (DSBs) have been shown to trigger the phosphorylation of serine 139 at the carboxy terminus of histone H2AX resulting in gamma-H2AX.

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).

Further, phosphorylation of H2AX (gamma-H2AX) has been shown to be important for either the recruitment or stable retention of DNA repair proteins to these intra-nuclear foci. We address here the relationship between DNA damage-induced hyper-phosphorylation of RPA and its intra-nuclear focalization, and whether gamma-H2AX is required for RPA's presence at these foci. DNA strand breaks trigger marked phosphorylation of histone H2AX (i.e. gamma-H2AX). While DNA double-strand breaks (DSBs) provide a strong stimulus for this event, the accompanying structural alterations in chromatin may represent the actual signal that elicits gamma-H2AX.

41 In search for FOXM1 targets that function downstream of H2AX phosphorylation, we found that FOXM1 regulates BRIP1 at the protein and mRNA levels 

How gamma-H2AX is removed from chromatin remains unknown. Here, we show that protein … H2AX phosphorylation and its role in DNA damage response upon phosphorylation H2AX became critical player in DNA damage response. Activity of 𝛾 H2AX could be summarized to following main points: accumulation of DNA damage signaling and repair proteins at DSBs The generation of DSBs triggers the relocalization of many DNA damage response (DDR) proteins such as MRE11/NBS1/RAD50, MDC1 Phosphorylation of many repair proteins has been shown to be important for their recruitment to DNA damage-induced intra-nuclear foci. Further, phosphorylation of H2AX (gamma-H2AX) has been shown to be important for either the recruitment or stable retention of DNA repair proteins to these intra-nuclear foci.
