INTRODUCTION
Small nuclear ribonucleoprotein complexes (abbreviated as U-snRNP) are essential for splicing of precursor mRNA molecules and snRNPB is one of several nuclear proteins which are found in common among U1, U2, U4/U6, and U5 small ribonucleoprotein particles (snRNPs). Autoantibodies from patients with systemic lupus erythematosus (SLE) recognize epitopes on snRNPB/B’.
IMMUNOLOGICAL FUNCTION
As an autoantigen, SmB/B’ binds with IgG-type human auto-antibodies.
