U2 small nuclear ribonucleoprotein B, U2 snRNP B, SNRPB2
The protein encoded by this gene associates with stem loopIV of U2 small nuclear ribonucleoprotein (U2 snRNP) in the presenceof snRNP-A. The encoded protein may play a role in pre-mRNAsplicing. Autoantibodies from patients with systemic lupuserythematosus frequently recognize epitopes on the encoded protein.Two transcript variants encoding the same protein have been foundfor this gene.
