Predicted to enable ribonucleoprotein complex binding activity. Predicted to be involved in maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be located in nucleolus and nucleoplasm. Predicted to be part of PeBoW complex and preribosome, large subunit precursor. Is an ortholog of human BOP1 (BOP1 ribosomal biogenesis factor).
