Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in several processes, including cellular response to leucine starvation; protein polyubiquitination; and regulation of TORC1 signaling. Predicted to be located in endosome. Predicted to be active in cytosol and endolysosome membrane. Is expressed in several structures, including central nervous system; genitourinary system; liver; and neural retina. Orthologous to human RNF167 (ring finger protein 167).
