Predicted to enable enzyme binding activity and phosphatidylinositol-4-phosphate binding activity. Predicted to be involved in several processes, including Golgi vesicle transport; cell adhesion molecule production; and cellular response to rapamycin. Located in several cellular components, including cytosol; endosome; and trans-Golgi network. Orthologous to human GOLPH3 (golgi phosphoprotein 3). [provided by Alliance of Genome Resources, Apr 2022]
