Predicted to enable protein homodimerization activity and ubiquitin protein ligase activity. Predicted to be involved in several processes, including cellular protein metabolic process; positive regulation of nitrogen compound metabolic process; and telomere maintenance. Predicted to act upstream of or within several processes, including common myeloid progenitor cell proliferation; positive regulation of protein polyubiquitination; and protein destabilization. Predicted to be located in cytoplasm. Predicted to be part of SCF ubiquitin ligase complex. Orthologous to human FBXO4 (F-box protein 4). [provided by Alliance of Genome Resources, Apr 2022]
