Predicted to enable 5S rRNA binding activity; identical protein binding activity; and p53 binding activity. Predicted to be involved in several processes, including protein localization to nucleus; regulation of cellular protein metabolic process; and regulation of intracellular signal transduction. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Predicted to be active in nucleolus. Predicted to colocalize with rDNA heterochromatin. Orthologous to human NOP53 (NOP53 ribosome biogenesis factor). [provided by Alliance of Genome Resources, Apr 2022]
