PIGN [ENSP00000350263]
 
phosphatidylinositol glycan anchor biosynthesis, class N; Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the first alpha-1,4-linked mannose of the glycosylphosphatidylinositol precursor of GPI-anchor (By similarity)
PIGO [ENSP00000339382]
 
phosphatidylinositol glycan anchor biosynthesis, class O; 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 (By similarity)
