General description

H2AX comprises 2-25% of the total H2A complement in human cells, whereas in the budding yeast it constitutes virtually all of the H2A molecules. It has N-terminal and C-terminal region with a central globular domain. The C-terminal region has sites for modification including acetylation, biotinylation and phosphorylation.

Immunogen

The synthetic peptide sequence is conjugated to KLH. The immunogen sequence is highly conserved (single amino acid substitution) in mouse histone H2AX.
synthetic phosphorylated peptide corresponding to the C-terminus (amino acids 134-142) of human histone H2AX (pSer139).

Application

Anti-phospho-Histone H2AX (pSer139) antibody produced in rabbit has been used in immunofluorescence and western blotting.

Biochem/physiol Actions

H2AX is critical for facilitating the assembly of specific DNA-repair complexes on damaged DNA. Ataxia-telangiectasia-mutated (ATM) is the major kinase involved in the phosphorylation of H2AX in response to DNA double-strand breaks. H2AX knockout mice are radiation sensitive and show retarted growth. They also are immune deficient with mutant males are infertile..

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
