**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor

**Definition:** Antigen(s) of small nuclear ribonucleoprotein (snRNP) complexes family of U1, U2, U4, U5, and U6, which contains a single nuclear RNA (snRNA) molecule, the associated proteins, and the seven core Smith (Sm) proteins. They can be considered as autoantigens and are commonly associated with the autoimmune disease systemic lupus erythematosus.
