http://purl.uniprot.org/citations/2526016http://www.w3.org/2000/01/rdf-schema#comment"Anti-Sm antibodies from a patient with systemic lupus erythematosus (SLE) were used to isolate cDNA clones encoding the snRNP-associated protein N from a rat brain derived cDNA library. The predicted primary structure of the 240 amino acid protein has a proline rich carboxyl terminus and shares a region of sequence similarity with other snRNP polypeptides, A and B/B'. Anti-Sm sera recognize a beta-galactosidase fusion protein containing only the carboxyl-terminal 80 amino acids of N; antibodies eluted from this fusion protein also react with A, B/B' and N on immunoblots, suggesting that these proteins share an Sm epitope located within this segment. Polyclonal antibodies raised against a 23 amino acid synthetic peptide derived from this conserved region of N recognize A, N and B/B' on immunoblots and can immunoprecipitate the Sm class of U snRNAs. These results confirm that this sequence defines a potential Sm epitope. RNA blotting analyses demonstrate that a 1.6 kb mRNA expressed predominantly in brain encodes the N polypeptide in both rats and humans. At low stringency rat N cDNA also hybridizes to a 1.3 kb mRNA species which encodes B/B', suggesting that N is structurally related to, but distinct from B/B'. Although B/B' proteins are thought to be expressed in all human cells, only N and B, but not B', are observed on immunoblots of human brain proteins probed with anti-Sm sera. The apparent difference in the complement of proteins associated with snRNP particles in human brain versus elsewhere suggests a possible mechanism for the regulation of brain-specific mRNA splicing."xsd:string
