Biomedical applications of glycosylphosphatidylinositol-anchored proteins
Glycosylphosphatidylinositol (GPI)-anchored proteins (GPI-APs) use a unique posttranslational modification to link proteins to lipid bilayer membranes. The anchoring structure consists of both a lipid and carbohydrate portion and is highly conserved in eukaryotic organisms regarding its basic characteristics, yet highly variable in its molecular details. The strong membrane targeting property h...
متن کاملProteomic analysis of glycosylphosphatidylinositol-anchored membrane proteins.
Glycosylphosphatidylinositol-anchored proteins (GPI-APs) are a functionally and structurally diverse family of post-translationally modified membrane proteins found mostly in the outer leaflet of the plasma membrane in a variety of eukaryotic cells. Although the general role of GPI-APs remains unclear, they have attracted attention because they act as enzymes and receptors in cell adhesion, dif...
متن کاملMetabolism of glycosylphosphatidylinositol-anchored proteins in Arabidopsis.
Although glycosylphosphatidylinositol (GPI)-anchored proteins have now been found in several plants, very little is known regarding their metabolism there. This report describes studies of the biosynthesis and turnover of arabinogalactan proteins, a class of abundant GPI-anchored proteins secreted by cultured Arabidopsis cells.
متن کاملLeukocyte adhesion and polarization: Role of glycosylphosphatidylinositol-anchored proteins
Leukocyte traffic out of the blood stream is crucial for an adequate immune response. Leukocyte extravasation is critically dependent on the binding of leukocyte integrins to their endothelial counterreceptors. This interaction enables the firm adhesion of leukocytes to the luminal side of the vascular wall and allows for leukocyte polarization, crawling and diapedesis. Leukocyte adhesion, pola...
متن کاملShedding and uptake of gangliosides and glycosylphosphatidylinositol-anchored proteins.
Gangliosides and glycosylphosphatidylinositol (GPI)-anchored proteins have very different biosynthetic origin, but they have one thing in common: they are both comprised of a relatively large hydrophilic moiety tethered to a membrane by a relatively small lipid tail. Both gangliosides and GPI-anchored proteins can be actively shed from the membrane of one cell and taken up by other cells by ins...
