SNRPB2 - small nuclear ribonucleoprotein polypeptide B2 Gene
Also Known as Msl1; U2B''
Species: Homo sapiens
About SNRPB2
This gene has 3 transcripts (splice variants), 248 orthologues and 1 paralogue. Ubiquitous expression in lymph node (RPKM 22.1), appendix (RPKM 20.1) and 25 other tissues.
Summary
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.
