Small nuclear ribonucleoproteins are highly conserved nuclear RNA-protein complexes that function in RNA processing in the nucleus, including pre-mRNA splicing and pre-mRNA 3'-end processing in the nucleoplasm, and pre-rRNA processing in the nucleolus[1] Antibodies to these proteins may be clinically significant in a number of rheumatological diseases.
"Systemic lupus erythematosus is characterized by production of autoantibodies to RNA or DNA–protein complexes such as small nuclear ribonucleoproteins (snRNPs). A role of Epstein–Barr virus in the pathogenesis has been suggested. Similar to Epstein–Barr virus, cytomegalovirus (CMV) infects the majority of individuals at a young age and establishes latency with a potential for reactivation...CMV [may have a role] in regulation of autoantibodies to snRNPs" [2]
Antibodies against the subclass U1 small nuclear ribonucleoproteins (anti-U1 snRNP OR anti-U1 RNP) are characteristic of mixed connective tissue disease.[3]
