General description
17 kDa observed
Histone H2A.X, also known as H2A/X, or H2A.X, and encoded by the gene name H2AFX and H2AX, is a variant of histone H2A and is similarly associated with genomic DNA. However, histone is structurally different from other members of the H2A family in possessing a C-terminal tail that contains the Ser139 residue that is phosphorylated in response to breaks in double-stranded DNA. The phosphorylation of H2A.X is a rapid process that is mediated by ATM/ATR proteins. As a member of the histone H2A family, histone H2A.x (H2A.x) is a variant histone H2A which replaces conventional H2A in a subset of nucleosomes. H2A.x is involved in the DNA repair of double-strand breakage (DSB) damage on nuclear DNA. After a double strand DNA break, H2A.x is rapidly phosphorylated at serine 139 by ATM kinase and becomes gamma-H2AFX. This phosphorylation step can extend up to several thousand nucleosomes from the actual site of the DSB and may mark the surrounding chromatin for recruitment of proteins required for DNA damage signaling and repair (1). As a part of posttranslational modifications during apoptosis caused by severe DNA damage, high expression of phosphorylated H2A.x is considered as an accurate indicator of apoptosis.
Immunogen

Phosphorylated histone H2AX (gammaH2AX) is generated in nucleosomes flanking sites of DNA double-strand breaks, triggering the recruitment of DNA-damage response proteins such as MDC1 and 53BP1. Here, we study shortened telomeres in senescent human cells. We show that most telomeres
