Predicted to enable ubiquitin conjugating enzyme binding activity and ubiquitin protein ligase activity. Predicted to be involved in several processes, including hematopoietic stem cell proliferation; positive regulation of protein targeting to mitochondrion; and protein polyubiquitination. Predicted to be located in nucleoplasm. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm. Orthologous to human ARIH2 (ariadne RBR E3 ubiquitin protein ligase 2).
