Predicted to enable enzyme binding activity; ubiquitin protein ligase activity; and zinc ion binding activity. Predicted to be involved in positive regulation of proteasomal ubiquitin-dependent protein catabolic process; protein polyubiquitination; and ubiquitin-dependent protein catabolic process. Predicted to be located in Lewy body and nuclear body. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm and nucleus. Orthologous to human ARIH1 (ariadne RBR E3 ubiquitin protein ligase 1). [provided by Alliance of Genome Resources, Apr 2022]
