Enables phosphatidylinositol binding activity. Predicted to be involved in several processes, including cytoskeleton-dependent cytokinesis; endosomal transport; and positive regulation of GTPase activity. Predicted to act upstream of or within cell division. Located in growth cone and neuronal cell body. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; genitourinary system; and immune system. Orthologous to human SNX18 (sorting nexin 18).
