Gangliosides, glycosphingolipids containing one or more sialic acid(s) in the glyco-chain, are involved in various important physiological and pathological processes in the plasma membrane. However, their exact functions are poorly understood, primarily because of the scarcity of suitable fluorescent ganglioside analogs. Here, we developed methods for systematically synthesizing analogs that behave like their native counterparts in regard to partitioning into raft-related membrane domains or preparations. Single-fluorescent-molecule imaging in the live-cell plasma membrane revealed the clear but transient colocalization and codiffusion of fluorescent ganglioside analogs with a fluorescently labeled glycosylphosphatidylinisotol (GPI)-anchored protein, human CD59, with lifetimes of 12 ms for CD59 monomers, 40 ms for CD59's transient homodimer rafts in quiescent cells, and 48 ms for engaged-CD59-cluster rafts, in cholesterol- and GPI-anchoring-dependent manners. The ganglioside molecules were always mobile in quiescent cells. These results show that gangliosides continually and dynamically exchange between raft domains and the bulk domain, indicating that raft domains are dynamic entities.

K.G.N.S., H.A., A.K., and M. Kiso conceived this research and designed experiments; N.K., H.A., M. Konishi, M. Koikeda, A.I., and M. Kiso developed organic synthesis methods and performed organic synthesis; R.S. and W.C. performed SPR experiments and analysis; K.G.N.S. examined ganglioside partitioning into DRM and Lo/Ld domains, studied colocalizations of CD59 patches with ganglioside analogues using epifluorescence, and performed all of the single-molecule tracking experiments; R.C. conducted most of the Lo/Ld partitioning measurements; T.K.F. set up the single-molecule tracking instrument and developed software for single-molecule colocalization detection; H.T. examined colocalizations of CD59 patches with ganglioside analogues using a confocal fluorescence microscope; F. Koichi, F. Keiko, and Y.Y. prepared GM3-depleted cell lines; K.G.N.S., H.A., A.K., and M. Kiso wrote the paper; and all authors participated in the revisions of the manuscript.
