The glycosylphosphatidylinositol (GPI) anchor is a membrane attachment structure of many
proteins and occurs in a wide variety of eukaryotes from yeasts to mammals. The structure of
the core of the GPI anchor is conserved in protozoa and mammals and so is its biosynthetic
pathway. A complementary DNA encoding a human protein termed PIG-A
(phosphatidylinositol glycan-class A) was cloned. PIG-A was necessary for synthesis of N-
acetylglucosaminyl-phosphatidylinositol, the very early intermediate in GPI-anchor …
