Histone H3 is a nuclear protein and a component of the nucleosome core that is essential for organizing genomic DNA in eukaryotic nuclei.
It is a globular protein that contains an unstructured N-terminal tail that extends outside of the nucleosome core and is subject to various post-translational modifications, including citrullination.
Histone H3 is subject to citrullination of arginine residues by peptidyl arginine deiminase 4 (PAD4) at positions 2, 8, 17, and 26, and this citrullination blocks methylation of these residues by protein-arginine methyltransferase 4 (PRMT4) and induces transcriptional repression of target genes.
Citrullinated histone H3 is a component of neutrophil extracellular traps (NETs) that acts as an autoantigen to induce the production of anti-citrullinated protein antibodies associated with various diseases such as sepsis, multiple sclerosis, rheumatoid arthritis, and multiple myeloma.
Increased serum levels of histone H3 citrullinated at R2, R8, and R17 have been found in patients with asthma and in septic shock patients where they are positively associated with a sequential organ failure assessment (SOFA) score and poor survival.
Sputum levels of histone H3 citrullinated at R2, R8, and R17 are increased in patients with rheumatoid arthritis, as well as in individuals identified as at risk for developing rheumatoid arthritis based on their seropositivity for IgA anti-citrullinated protein antibodies (ACPAs).
