Enables ionotropic glutamate receptor binding activity and phosphatidylinositol-3-phosphate binding activity. Involved in several processes, including endosome to plasma membrane protein transport; negative regulation of inward rectifier potassium channel activity; and positive regulation of AMPA glutamate receptor clustering. Located in several cellular components, including cytosol; early endosome; and postsynaptic density. Orthologous to human SNX27 (sorting nexin 27). [provided by Alliance of Genome Resources, Apr 2022]
