Predicted to enable ribonucleoprotein complex binding activity. Predicted to be involved in several processes, including regulation of cell cycle; regulation of signal transduction by p53 class mediator; and ribosomal large subunit biogenesis. Predicted to act upstream of or within rRNA processing and ribosomal large subunit biogenesis. Predicted to be located in chromosome; nucleolus; and nucleoplasm. Predicted to be part of PeBoW complex and preribosome, large subunit precursor. Orthologous to human BOP1 (BOP1 ribosomal biogenesis factor). [provided by Alliance of Genome Resources, Apr 2022]
