Splicing factor, arginine/serine-rich 11 is a protein that in humans is encoded by the SFRS11gene.
This gene encodes 54-kD nuclear protein that contains an arginine/serine-rich region similar to segments found in pre-mRNA splicing factors. Although the function of this protein is not yet known, structure and immunolocalization data suggest that it may play a role in pre-mRNA processing.
