| Research Abstract |
Bio-membrane consists of membrane proteins and a various variety of lipids. Nano-domains that are called "Raft" are created in such heterogeneous system. The raft contains a lot of cholesterols and Sphingo-lipids. The functions of Amyloid Precursor Proteins (APP), are related to the Alzheimer disease, are affected by the raft. We have investigated the interaction between lipid and APP, and the interaction of membrane proteins in the raft. Our results suggested that the cholesterols are collected around the APP, especially Gly-xxx-Gly motif, and the cholesterols assist the association of APP.
