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. Located in phagophore assembly site. Is expressed in several structures, including central nervous system and retina. Orthologous to human WIPI1 (WD repeat domain, phosphoinositide interacting 1).
