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 act upstream of or within rRNA processing. Predicted to be located in intermediate filament cytoskeleton and nucleolus. Predicted to be active in nucleus. Orthologous to human NOL9 (nucleolar protein 9).
