Predicted to enable RNA binding activity. Predicted to be involved in mRNA 5'-splice site recognition and regulation of alternative mRNA splicing, via spliceosome. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleus. Predicted to be active in nuclear speck. Orthologous to human SRSF12 (serine and arginine rich splicing factor 12). [provided by Alliance of Genome Resources, Apr 2022]
