General description
Histone H2AX (UniProt: P16104; also known as H2a/x, Histone H2A.X) is encoded by the H2AFX (also known as H2AX) gene (Gene ID: 3014) in human. Histones are highly conserved basic nuclear proteins that are responsible for the nucleosome structure of chromatin in eukaryotes. They play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which DNA is wrapped in repeating units, called nucleosomes, which limits DNA accessibility to the cellular machineries that require DNA as a template. The histone H2A.X is a variant member of the H2A family of histones that is distinguished from other H2A histones by a unique carboxy-terminal sequence. This unique sequence is highly conserved throughout eukaryotic evolution and is rapidly phosphorylated by ATM or ATR at Serine 139 in mammals in response to DNA double-strand breaks. H2A.X phosphorylation is important in the formation of a stable repair complex at the site of DNA damage. Phosphorylation of H2A.X is important in the formation of a stable repair complex at the site of DNA damage. This phosphorylation is a very rapid response to DNA damage, occurring within as little as one minute after exposure to ionizing radiation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
