Predicted to enable phosphatidylinositol-3,5-bisphosphate binding activity; phosphatidylinositol-3-phosphate binding activity; and phosphatidylinositol-5-phosphate binding activity. Predicted to be involved in several processes, including autophagy of mitochondrion; autophagy of nucleus; and protein localization to phagophore assembly site. Predicted to act upstream of or within protein lipidation involved in autophagosome assembly and xenophagy. Predicted to be located in autophagosome; nucleoplasm; and phagophore assembly site. Predicted to be part of protein-containing complex. Predicted to be active in cytosol and phagophore assembly site membrane. Predicted to be extrinsic component of membrane. Predicted to colocalize with membrane. Orthologous to human WIPI2 (WD repeat domain, phosphoinositide interacting 2). [provided by Alliance of Genome Resources, Apr 2022]
