Sp100 nuclear antigen is an interferon stimulated antigen found in the cell nuclei of many human and higher animal cells. Autoantibodies directed against Sp100 are often found in patients with primary biliary cirrhosis. [1] Histologically Sp100 'dots' regions of the cell nucleus. Viral infection and mitogens affect the expression of the Sp100 ...

Anti-sp100 antibodies are found in approximately 20–30% of primary biliary cirrhosis (PBC). They are found in few individuals without PBC, and therefore are a very specific marker of the disease. The sp100 antigen is found within nuclear bodies; large protein complexes in the nucleus that may have a role in cell growth and differentiation. [47]
