Notes: Nucleosomes are the basic repeating units of chromatin in which DNA is wrapped twice around a histone octamer consisting of two copies of each of the core histones, H2A, H2B, H3, and H4.{17798} Peripheral proteins, including the histone H1, interact with nucleosomes to affect chromatin structure. Histones undergo many modifications, which include acetylation, methylation, and phosphorylation, that are important for the regulation of gene transcription.{17798} Citrullination is another important post-translational modification that is catalyzed by the pepitylarginine deiminases PAD4 and PAD2. Hypercitrullination of histones leads to the development of neutrophil extracellular traps (NETs), which are a part of the inflammatory response.{28015,28019} Neutrophils release these NETs to trap and eradicate bacteria and fungi. Failure to clear citrullinated proteins and NET components following inflammation can result in the production of autoantibodies and anti-citrullinated protein antibodies.{28017} The persistence of these antibodies and citrullinated proteins is associated with a number of human diseases including rheumatoid arthritis, systemic lupus erythematosus, Alzheimer’s disease, and multiple sclerosis.{28018} This product contains a mixture of H1, H2A, H2B, H3, and H4 histones isolated from calf thymus. The mixture is modified by PAD4 enzyme, which is subsequently depleted by affinity chromatography.
