Predicted to enable GTPase binding activity and ubiquitin protein ligase binding activity. Acts upstream of or within several processes, including autophagy; negative regulation of neuron apoptotic process; and neural tube development. Located in axoneme; cytosol; and phagocytic vesicle. Is expressed in main olfactory bulb. Orthologous to human AMBRA1 (autophagy and beclin 1 regulator 1). [provided by Alliance of Genome Resources, Apr 2022]
