INTRODUCTION
Histones are proteins that package DNA into nucleosomes and are responsible for maintaining the shape and structure of a nucleosome.
There are five families of histones known to date, H1/H5, H2A, H2B, H3, and H4. H2A, along with H2B, H3 and H4, is considered as a core histone.
Anti-histone autoantibodies are found in 50%-70% of patients with systemic lupus erythematosus (SLE) and in more than 95% of patients with drug-induced lupus erythematosus.
IMMUNOLOGICAL FUNCTION
As an autoantigen, H2A binds with IgG-type human auto-antibodies.
