SNRPB encodes the human gene, Small nuclear ribonucleoprotein polypeptides B and B1. It may also be known as: Small nuclear ribonucleoprotein-associated proteins B and B'; Sm protein B/B'; Sm-B/B'; SmB/B'; snRNP-B; COD; SNRPB1; SmB/SmB'. The encoded protein has an amino acid length of 240 and a mass of 24.6 kDa. SNRPB is a member of the SnRNP SmB/SmN family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
