SNRPB

Small nuclear ribonucleoprotein-associated proteins B and B' is a is_associated_with::protein that in humans is encoded by the SNRPB is_associated_with::gene.

Function
The protein encoded by this gene is one of several nuclear proteins that 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 encoded protein may also play a role in pre-mRNA splicing or snRNP structure. Autoantibodies from patients with systemic lupus erythematosus frequently recognize epitopes on the encoded protein. Two transcript variants encoding different isoforms (B and B') have been found for this gene.

Interactions
SNRPB has been shown to interact with is_associated_with::DDX20 and is_associated_with::Coilin.
