Small nuclear ribonucleoprotein-associated proteins B and B', snRNP-B, Sm protein B/B', Sm-B/B', SmB/B', SNRPB, COD, SNRPB1, SmB/SmB'.


SNRPB is one of several nuclear proteins which are found in common among U1, U2, U4/U6, and U5 small ribonucleoprotein particles (snRNPs). These snRNPs are involved in pre-mRNA splicing, and the SNRPB protein may also have a role in pre-mRNA splicing or snRNP structure. SNRPB binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner. SNRPB functions in the U7 snRNP complex which is involved in histone 3'-end processing.


SNRPB Human Recombinant produced in SF9 is a glycosylated, polypeptide chain having a calculated molecular mass of 25.4 kDa which migrates at 30kDa on SDS-PAGE. SNRPB is expressed with a -6x His tag and purified by proprietary chromatographic techniques.
