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). 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). The H2AX variant represents between 2-25% of total H2A (1-3). Human H2AX protein is 143 amino acids in length and has a theoretical molecular weight of 15 kDa (5). As a result of DSBs, H2AX becomes phosphorylated at serine-139 and gamma H2AX is generated as a response to genomic instability (1-4). Gamma H2AX and its phosphorylation can be detected through western blotting and immunofluorescence, serving as a biomarker for DSB frequency (1-4). Ataxia telangiectasia mutated (ATM) is considered a key protein for H2AX phosphorylation (1-4). Upon the phosphorylation and formation of gamma H2AX, many repair proteins become associated including breast cancer 1 protein (BRCA1), NBS1 (Nijmegen breakage syndrome 1)/hMRE11 (human meiotic recombination 11 protein)/ hRAD50 (N/M/R) repair complex, and 53BP1 (p53 binding protein 1) (1-4). Gamma H2AX detection assays are currently utilized for a variety of purposes, from studying DNA repair to drug development and radiation biodosimetry (4).
