H2AX 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. WebHistone H2A.X maps to the 11q23.2-q23.3 region of the human chromosome. Histone H2A.x contributes to histone-formation and therefore the structure of DNA. Histone H2A variant H2A.x specifically regulates the interaction of MDC1 (mediator of DNA damage checkpoint protein 1), a DNA repair protein to the sites of DNA damage. Synonyms cell way
