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 ...
WebHistone H2AX phosphorylation on a serine four residues from the carboxyl terminus (producing γH2AX) is a sensitive marker for DNA double-strand breaks (DSBs). DSBs may lead to cancer but, paradoxically, are also used to kill cancer cells.
