Protein-coding gene in the species Homo sapiens
U2 small nuclear ribonucleoprotein B is a protein that in humans is encoded by the SNRPB2 gene .[ 5] [ 6]
The protein encoded by this gene associates with stem loop IV of U2 small nuclear ribonucleoprotein (U2 snRNP) in the presence of snRNP-A'. The encoded protein may play a role in pre-mRNA splicing. Autoantibodies from patients with systemic lupus erythematosus frequently recognize epitopes on the encoded protein. Two transcript variants encoding the same protein have been found for this gene.[ 6]
