Colworth Medal Lecture. Glycosyl-phosphatidylinositol membrane anchors: the tale of a tail.

Over the last few years we have learned of a new type of membrane anchorage for cell-surface proteins, the GPI anchors. We now have a good idea of their structure and biosynthesis, and indications of their specific functions in protozoa and mammals. The widespread distribution of GPI membrane anchors throughout the eukaryotes has led many researchers to work on various aspects of GPI anchors. This has led to the widespread exchange of data, ideas and techniques which has made the field a pleasure to work in.
