WebJun 9, 2024 · Glycosylphosphatidylinositol (GPI) anchors are a unique class of complex glycolipids that anchor a great variety of proteins to the extracellular leaflet of plasma membranes of eukaryotic cells. These anchors can exist either with or without an attached protein called GPI-anchored protein (GPI-AP) both in vitro and in vivo. WebGlycosylphosphatidylinositol-anchored proteins (GPI-anchored proteins) are attached to a GPI complex molecular group via an amide linkage to the protein's C-terminal carboxyl group. This GPI complex consists of … WebGPI anchors impart to their attached proteins the ability to be shed from the cell surface in soluble form through the action of cellular or serum GPI-cleaving enzymes.
