Predicted to enable polynucleotide 5'-hydroxyl-kinase activity. Predicted to be involved in cleavage in ITS2 between 5.8S rRNA and LSU-rRNA of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be located in intermediate filament cytoskeleton and nucleolus. Predicted to be active in nucleus. Orthologous to human NOL9 (nucleolar protein 9).
