The human spliceosomal Sm B/BЈ proteins are essential for the biogenesis of the snRNP particles. B/BЈ proteins contain several clusters of the PPPPGM/IR sequence, which occurs within the C-terminus of Sm B/BЈ. This sequence is very similar to the PPPPPGHR sequence of the cytoplasmic tail of the CD2
