Predicted to enable nuclear receptor binding activity; phosphatidylinositol phosphate binding activity; and signaling receptor binding activity. Predicted to be involved in several processes, including autophagy of mitochondrion; protein localization to phagophore assembly site; and vesicle targeting, trans-Golgi to endosome. Predicted to be located in bounding membrane of organelle; phagophore assembly site; and trans-Golgi network. Predicted to be active in cytosol and phagophore assembly site membrane. Predicted to be extrinsic component of membrane. Orthologous to human WIPI1 (WD repeat domain, phosphoinositide interacting 1). [provided by Alliance of Genome Resources, Apr 2022]
