Predicted to enable GPI anchor binding activity; GPI-mannose ethanolamine phosphate phosphodiesterase activity; and manganese ion binding activity. Predicted to be involved in GPI anchor biosynthetic process and endoplasmic reticulum to Golgi vesicle-mediated transport. Predicted to be located in several cellular components, including cis-Golgi network; endoplasmic reticulum exit site; and endoplasmic reticulum-Golgi intermediate compartment. Orthologous to human MPPE1 (metallophosphoesterase 1). [provided by Alliance of Genome Resources, Apr 2022]
