Predicted to enable ubiquitin conjugating enzyme binding activity and ubiquitin protein ligase activity. Predicted to be involved in ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within protein ubiquitination. Predicted to be located in membrane. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm. Orthologous to human RNF217 (ring finger protein 217).
