The U1 small nuclear ribonucleoprotein (snRNP) particle consists of an RNA backbone and eleven associated proteins. Both the RNA and some of the proteins are immunogenic in patients suffering from systemic lupus erythematosus or mixed connective tissue disease. An overview is given of the U1 snRNP particle with respect to its structure and function as well as its autoantigenicity.
