Autoantibodies to histone antigens have been described in patients with idiopathic and drug-induced SLE, rheumatoid arthritis, and other conditions. The presence of autoantibodies to histones are frequently found in several rheumatic disorders. In one study, the predominant responses to histones in SLE sera were to...

Histones are a family of basic proteins found in all eukaryotic nuclei that are associated with eukaryotic DNA. The five major types of histone are H1, H2A, H2B, H3 and H4. The latter four, which comprise nucleosome core, are evolutionarily conserved, while the linker histone H1 exhibits greater sequence diversity...

H2AX comprises approximately 2-25% of the histone H2A pool in mammalian cells. The extended C-terminal tail of H2AX contains a serine (Ser139) embedded in an conserved SQE motif, which is rapidly phosphorylated at sites of double strand breaks and stalled replication forks. Phosphorylated H2AX may serve to recruit...

H2AFX is basic nuclear protein that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker...
