Transfer of exogenous glycosylphos-phatidylinositol (GPI)-linked molecules to plasma membranes

Robinson, P. J.
Published in Trends in Cell Biology. 1996, vol. 6, no. 5, p. 163-167
Abstract Purified GPI-linked molecules incorporate spontaneously in vitro into mammalian cell plasma membranes. Recent evidence suggests that the transferred molecules insert stably into the external leaflet of the acceptor cell plasma membrane through their acyl chains and behave subsequently in a way similar to endogenous GPI-linked molecules. Transfer of GPI-linked proteins between cells has also been documented in vivo and may explain the uptake by host cells o f pathogen-derived virulence factors carrying a GPI anchor. In this comment article, Subburaj Ilangumaran, Peter Robinson and Daniel Hoessli review what is known about GPI transfer and discuss the use of GPI transfer for transient cell-surface expression of foreign proteins.
