alternative products:Additional isoforms seem to exist,function:Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the GPI third mannose which links the GPI-anchor to the C-terminus of the proteins by an amide bond.,pathway:Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis.,similarity:Belongs to the PIGG/PIGN/PIGO family. PIGO subfamily.,subunit:Forms a complex with PIGF. PIGF is required to stabilize PIGO.,
