Outline Activities
To totally understand biomembranes including membrane proteins, we performed integrated analyses of membranes by using various methods of not only analytical chemistry but also organic chemistry, chemical biology, and structure biology. In more detail, we are studying lipid rafts and lipid diversity for the basic understanding of biomembranes, and mechanism of action of membrane-acting drugs such as anesthetics.

Fujiwara, Akihiro Kusumi, Michio Murata, Raft-based sphingomyelin interactions revealed by new fluorescent sphingomyelin analogs, Journal of Cell Biology, 10.1083/jcb.201607086, 216, 4, 1183-1204, 2017.04, Sphingomyelin (SM) has been proposed to form cholesterol-dependent raft domains and sphingolipid domains in the plasma membrane (PM). How SM contributes to the formation and function of these domains remains unknown, primarily because of the scarcity of suitable fluorescent SM analogs. We developed new fluorescent SM analogs by conjugating a hydrophilic fluorophore to the SM choline headgroup without eliminating its positive charge, via a hydrophilic nonaethylene glycol linker. The new analogs behaved similarly to the native SM in terms of their partitioning behaviors in artificial liquid order-disorder phase-separated membranes and detergent-resistant PM preparations. Single fluorescent molecule tracking in the live-cell PM revealed that they indirectly interact with each other in cholesterol- and sphingosine backbone-dependent manners, and that, for ~10-50 ms, they undergo transient colocalization-codiffusion with a glycosylphosphatidylinositol (GPI)-anchored protein, CD59 (in monomers, transient-dimer rafts, and clusters), in CD59-oligomer size-, cholesterol-, and GPI anchoring-dependent manners. These results suggest that SM continually and rapidly exchanges between CD59-associated raft domains and the bulk PM..
