This appears to be true even after exposure to the alkylating agent MNNG that does not cause direct double-strand breaks …
Staining Against Phospho-H2AX (γ-H2AX) as a Marker for DNA
WebH2AX is a variant of the H2A protein family and is a component of the histone octomer in nucleosomes. H2AX is phosphorylated by kinases such as ataxia telangiectasia mutated (ATM) and ATM-Rad3-related (ATR) in the PI3K pathway. Gamma-H2AX is the first step in recruiting and localizing DNA repair proteins. DSBs can be induced by mechanisms such ...
