Plasmalemmal caveolae and GPI-anchored membrane proteins
Abstract
Caveolae are essential endocytic organelles that use glycosyl-phosphatidyl-inositol (GPI)-anchored membrane proteins to concentrate low molecular weight substances before delivery to the cell. Caveolae and GPI-anchored proteins are uniquely adapted for this task. Recent advances suggest that this endocytic pathway also has an important role in modulating the interaction of a cell with its environment. Many vital functions that occur in this organelle remain to be discovered.
