Enables 5S rRNA binding activity; identical protein binding activity; and p53 binding activity. Involved in several processes, including negative regulation of transcription, DNA-templated; regulation of cellular protein metabolic process; and regulation of intracellular signal transduction. Located in cytosol; fibrillar center; and nucleoplasm. Colocalizes with rDNA heterochromatin.
