The protein encoded by the U1SNRNPBP gene is a homolog of U1-snRNP binding protein. The N-terminal half contains a RNA recognition motif and the C-terminal is rich in Arg/Asp and Arg/Glu dipeptides; a characteristic of a variety of splicing factors. This protein is a component of the U11/U12 small nuclear ribonucleoproteins (snRNP) that form part of the U12-type spliceosome. This gene is differentially expressed in a variety of human tissues. Alternative splicing results in multiple transcript variants encoding distinct proteins.
