Autoantibodies to DEK oncoprotein in a patient with systemic lupus erythematosus and sarcoidosis

Abstract excerpt

A patient was identified with an unusual autoimmune syndrome consisting of systemic lupus erythematosus and sarcoidosis. Her serum contained extremely high levels of autoantibodies to the DEK protooncogene product. The patient's serum was used to clone a dek complementary DNA, which was expressed as a histidine-tagged fusion protein in Escherichia coli.
