gpi-anchor membrane lipid modification
Overview
GPI anchors are glycolipid modifications attaching proteins to the outer leaflet of cell membranes.
Structure
The conserved core structure is ethanolamine-PO4-Man-Man-Man-GlcN-acyl-PI, with variable side chains.
Biological Significance
GPI-anchored proteins include CD59, alkaline phosphatase, and prion protein. GPI anchor deficiency causes paroxysmal nocturnal hemoglobinuria.
