Predicted to enable several functions, including protein homodimerization activity; ubiquitin protein ligase activity; and ubiquitin protein ligase binding activity. Predicted to be involved in several processes, including DNA metabolic process; protein ubiquitination; and regulation of nucleobase-containing compound metabolic process. Predicted to be located in chromosome, telomeric region; cytoplasm; and nucleoplasm. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytosol; nucleus; and site of double-strand break. Orthologous to human RNF8 (ring finger protein 8). [provided by Alliance of Genome Resources, Apr 2022]
