Predicted to enable phosphatidylinositol-3-phosphate binding activity; phosphatidylinositol-4-phosphate binding activity; and phosphatidylinositol-5-phosphate binding activity. Involved in autophagosome maturation; regulation of glycogen metabolic process; and regulation of lipid metabolic process. Predicted to be located in cytoplasmic vesicle and membrane. Predicted to be active in autophagosome membrane. Orthologous to human RUBCNL (rubicon like autophagy enhancer). [provided by Alliance of Genome Resources, Apr 2022]
