Zielbeschreibung

Histone H2AX (UniProt: P16104; also known as H2a/x, Histone H2A.X) is encoded by the H2AX (also known as H2AFX) gene (Gene ID: 3014) in human. The histone H2A.X protein 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 the fourth residue from the carboxy-terminus (serine 139 in mammalian H2A.X) in response to DNA double-strand breaks (DSBs). Histone H2AX plays a crucial role in the maintenance of genome stability and the DNA damage response (DDR). H2AX is ubiquitously expressed in almost all eukaryotic cells and is primarily localized in the cell nucleus, where it plays a crucial role in the packaging and organization of DNA within chromatin. Phosphorylation of H2A.X is important in the formation of a stable repair complex at the site of DNA damage. H2A.X phosphorylation is a very rapid response to DNA damage, occurring within as little as one minute after exposure to ionizing radiation. Phosphorylation of H2A.X occurs irrespective of the cause of the DNA DSBs and phospho-H2A.X has been observed in response to environmental stresses that result in DSBs as well as programmed cellular events, including DNA rearrangement and apoptosis. Histone H2AX phosphorylated at serine 139 (gamma H2AX) is a hallmark of DNA damage, signaling the presence of DNA double-strand breaks and global replication stress in mammalian cells. The small size and great affinity for gamma H2AX, allows for efficient electroporation of this C6B nanobody in living cells and, detection of gamma H2AX foci in non-fixed live cells in real time imaging.
