Gpi Anchor Structure
Glycosylphosphatidylinisotol (GPI) anchored proteins are membrane bound proteins found throughout the animal kingdom. GPI anchored proteins are linked at their carboxyterminus through a phosphodiester linkage of phosphoethanolamine to a trimannosyl-non-acetylated glucosamine (Man3-GlcN) core.
