About SNRPB2

Cytogenetic location: 20p12.1 Genomic coordinates (GRCh38): 20:16,730,026-16,742,564 (from NCBI)

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.
