Predicted to enable small GTPase binding activity and ubiquitin protein ligase activity. Involved in cellular response to amino acid starvation; negative regulation of TORC1 signaling; and positive regulation of autophagy. Predicted to be located in lysosome. Predicted to be integral component of organelle membrane. Predicted to be active in lysosomal membrane. Is expressed in diencephalon lateral wall mantle layer; diencephalon mantle layer; hypothalamus mantle layer; hypothalamus ventricular layer; and thalamus mantle layer. Orthologous to human RNF152 (ring finger protein 152). [provided by Alliance of Genome Resources, Apr 2022]
