Enables several functions, including SUMO polymer binding activity; TBP-class protein binding activity; and nuclear receptor binding activity. Involved in several processes, including cellular response to gamma radiation; cellular response to hydroxyurea; and protein ubiquitination. Located in cytosol and nucleoplasm. Colocalizes with PML body. Orthologous to human RNF4 (ring finger protein 4). [provided by Alliance of Genome Resources, Apr 2022]
