WebbThe most abundant snRNA species exist as a closely related set of RNA-protein complexes called small nuclear ribonucleoproteins (snRNPs) 9. snRNPs are the antigens recognised by antibodies from some patients with lupus erythematosus (LE), an autoimmune rheumatic disease 10,11. WebbMany of these small nuclear RNA (snRNA) species, which range in size from about 90 to 220 nucleotides, have been well-characterised biochemically3–6, and some sequenced7,8.
