Predicted to enable ubiquitin conjugating enzyme binding activity and ubiquitin protein ligase 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 intracellular membrane-bounded organelle. Predicted to be part of ubiquitin ligase complex. Predicted to be active in Golgi apparatus. Orthologous to human RNF144A (ring finger protein 144A). [provided by Alliance of Genome Resources, Apr 2022]
