Enables 5S rRNA binding activity; identical protein binding activity; and p53 binding activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; regulation of intracellular signal transduction; and regulation of primary metabolic process. Located in cytosol; nuclear lumen; and rDNA heterochromatin. [provided by Alliance of Genome Resources, Jul 2025]
