Predicted to enable small GTPase binding activity and ubiquitin protein ligase activity. Predicted to be involved in several processes, including Golgi organization; cellular protein metabolic process; and positive regulation of protein catabolic process. Predicted to be located in endoplasmic reticulum and nuclear body. Predicted to be active in Golgi membrane and nucleus. Is expressed in central nervous system; eye; foregut; skin; and testis. Orthologous to human HACE1 (HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1). [provided by Alliance of Genome Resources, Apr 2022]
