Summary: Enables U3 snoRNA binding activity and U4 snRNA binding activity. Involved in mRNA splicing, via spliceosome and maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Located in nucleolus. Part of U4/U6 x U5 tri-snRNP complex; box C/D methylation guide snoRNP complex; and small-subunit processome. Used to study cancer. Orthologous to human SNU13 (small nuclear ribonucleoprotein 13).
